Introducing: The Grand Seiko SBGX355 “Snowflake Quartz”

Quartz is having something of a quiet comeback. After decades of scorn and contempt, many have come to appreciate the ease of use that quartz provides. Furthermore, not all quartz watches are the same. Today’s new Grand Seiko SBGX355, already nicknamed “Snowflake Quartz,” uses the brand’s famed 9F62 movement and comes in a highly wearable […] Visit Introducing: The Grand Seiko SBGX355 “Snowflake Quartz” to read the full article.

You may have your own opinion about quartz watches, but Grand Seiko has certainly elevated the movement technology to a whole different level. And their new 9F-powered GMT models make a compelling case for half of a two-watch collection, or even a one-watch collection, depending on your needs. A quartz GMT certainly fits the bill … ContinuedThe post VIDEO: Grand Seiko make a compelling case for a one-watch collection with their new quartz GMTs appeared first on Time+Tide Watches.

INTRODUCING: The Grand Seiko SBGX341 is a formidable everyday option

Are there any manufacturers that do quartz better than Grand Seiko? The brand, after all, makes their own quartz crystals in-house and upholds them to the most rigorous standards of accuracy – the 9F series of movements, for example, are regulated to run within +/- 10 seconds per year at a minimum. The deviation is … ContinuedThe post INTRODUCING: The Grand Seiko SBGX341 is a formidable everyday option appeared first on Time+Tide Watches.

Grand Seiko Introduces the 60th Anniversary Limited Editions

Originally unveiled as a sub-brand of Seiko in 1960 dedicated entirely to high-precision wristwatches – and only sold in Japan for most of that time – Grand Seiko has now become an independent brand. This year is the 60th anniversary of its founding, and the occasion is being commemorated with a quartet of limited editions (with perhaps more to come later in the year), including two quartz watches powered by the 9F85, a new, top-of-the-line quartz movement. All of the anniversary editions feature a dial in dark blue, one of Grand Seiko’s signature colours, albeit executed in different materials or finishes, ranging from a stamped pattern to mother of pearl. All of the men’s models also have a red seconds hand, creating a red and blue aesthetic that’s uncommon for Grand Seiko. The flagship 60th anniversary watch is the Heritage Collection Hi-Beat 36000 Limited Edition (SBGH281), a variant of the 44GS “modern reinterpretation” that features broad, mirror-polished case flanks that are steeply sloped, a distinguishing characteristic of the 44GS case style. It’s powered by the 9S85, an automatic movement operated at 36,000 beats per hour, hence the “Hi-Beat” label.  Only 1,500 will be made. The Hi-Beat limited edition also features a gold “GS” logo on the dial The other mechanical model in the anniversary line-up is the Elegance Collection Women’s Automatic Limited Edition (STGK015), powered by the 9S27 automatic movement. Its dial is dark-blue mother...

Introducing: De Bethune DB25Vxs Silver Moon And DB28xs Dark Sand Hodinkee
De Bethune DB25Vxs Silver Moon Apr 21, 2026

Introducing: De Bethune DB25Vxs Silver Moon And DB28xs Dark Sand

What We Know While not at Watches and Wonders this year, De Bethune was one of a number of brands jumping on the release bandwagon this week with a few new versions. Today, we're taking a look at two new pieces from the brand. De Bethune's DB25Vxs Silver Moon keeps some of the brand's futuristic design with the skeletonized lugs, while DB28xs Dark Sand picks up where the brand's DB28xs "Steel Wheels" left off. Let's start with the slightly more traditional watch first. The DB25Vxs Silver Moon trims the DB25L case size down to 40mm and changes the dial around a bit. It's been 17 years since the DB25L came out, so it was time for an update. The watch features a mirrored blued-titanium surround with gold stars, drawing the eye to the mirror-polished steel and blued-titanium spherical moonphase at 12 o'clock, which is accurate to 1 day every 122 years. The domed outer track features printed, slightly dressy Breguet numerals and a minute track for the gold hour and minute hands (in Breguet style as well) while the central dial features a barleycorn guilloché. Inside the 40.6mm by 11.2mm mirror-polished grade 5 titanium case is a caliber running at 4Hz with a 6-day power reserve. While a lot of my friends gravitate more toward that traditional aesthetic from De Bethune, my eyes immediately go for the more extreme De Bethunes, like the DB28xs Dark Sand, with the hinged lugs and (yes, somewhat divisive) arch design on the front. The DB28xs Dark Sand also has a 6-day power reserve...

Watches & Wonders: the Nomos Tangente neomatik 38 Update Brings the Date Ring and the Midas Touch to a Smaller Size Worn & Wound
Nomos Tangente neomatik 38 Update Apr 13, 2026

Watches & Wonders: the Nomos Tangente neomatik 38 Update Brings the Date Ring and the Midas Touch to a Smaller Size

In the Nomos Glashütte lineup, the Tangente is one that brings it all: the allure of 18-karat gold, sizes that range from 33 to 42mm, a unique and subtle date ring, even a few models rated to 1,000 feet of water resistance.  Now the most popular features merge into one aptly-named release: the Tangente neomatik 38 Update, making its debut at this year’s Watches & Wonders. It begins with the mid-sized case that measures 38.5 millimeters, hitting the sweet spot of popularity and balanced proportions. And it’s now available in 18-karat gold, alongside the stainless steel seen on most Tangente models.  “By introducing Tangente Update in gold,” says Nomos CEO Uwe Ahrendt, “we are also responding to a frequently heard request for modern dress watches, crafted from precious metal.”    The most important feature in this new model is adapting the date ring into a smaller format. The date ring, which Nomos calls Update, circles the edge of the dial with oval windows marking the days of the month, indicating the current date with two red markers on either side.  Previously, the date ring was formerly only available in a 41mm size, or in an unusual two-date system that debuted in 2024. What’s under the skin and behind that 18-karat gold case is the neomatik caliber DUW 6101: an automatic-wind movement with up to 42 hours of power reserve that now gets the same date ring system adapted into a smaller size (just 7.4mm in height, a squeak below the 7.8mm size of the ...

Grand Seiko Introduces the SBGX359 and SBGX361, Featuring their Smallest and Thinnest Quartz Movement Yet Worn & Wound

Grand Seiko Introduces the SBGX359 and SBGX361, Featuring their Smallest and Thinnest Quartz Movement Yet

While design hallmarks have come and gone, few say “Grand Seiko” quite like the iconic Snowflake dial, first introduced in 2005. Inspired by the frosty Hotaka mountain range in the brand’s home prefecture, Nagano, light plays across the fine texture to emphasize the slight variations in depth on the surface of the dial. The result is nothing short of stunning, and helped shape Grand Seiko and their philosophy of the “Nature of Time”. So how do you build on an icon? You introduce tasteful variations. Easier said than done, of course, but Grand Seiko has done it successfully before, by introducing the Skyflake dial, a light blue version of the Snowflake. And now, we have two new Snowflake and Skyflake models to showcase the evolution of the icon: the SBGX359 and SBGX361, in a compact 33mm case, making them the smallest in the Grand Seiko 9F line yet. Even more impressive is the 9.1mm thickness, which is only possible thanks to the Caliber 9F51 quartz movement, which is the first new movement in the 9F line since 2020, and allows for an accuracy of ± 10 seconds a year. In natural Grand Seiko fashion, each movement is hand-assembled by watchmakers at the Shinshu Watch Studio at the brand’s Shiojiri facility and feature three-month aged quartz crystals and a manual regulation switch for accuracy fine-tuning during servicing. All of that is to say that this is not a basic quartz movement; it’s a Grand Seiko quartz movement, which is sure to excel in both function ...

Interview: Sylvain Berneron on Building a Brand, and Rethinking Modern Watchmaking

Every few years, a new independent hits the scene with something that hits just the right notes to get all the factions of the watch world vibrating at the same frequency. However, no recent newcomer has managed to unite the watch echo chamber the way Swiss independent Berneron has.  When Berneron unveiled their debut offering, the Mirage, in 2023, it was universally lauded as the most intriguing and refreshing new watch seen in ages. The Mirage was a legitimately unique take on upscale watchmaking, with a striking aesthetic and design narrative as unexpected as its asymmetrical shape and wildly ambitious bespoke movement. The Mirage’s styling was initially met with comparisons to the Cartier Crash, but the reality is its melted case shape was an elegant solution for housing the watch’s impressive mechanics–a case shrink-wrapped around a new caliber that was designed from scratch, free from the rules of traditional movement design.  The Mirage was a helluva of a breakout hit; it had mystique, it was technically impressive, and it was different without resorting to arbitrary design choices. The Mirage’s success would be difficult to replicate, but with the Quantième, Berneron has both side-steped the sophomore slump and cemented the reputation of its founder and Creative Director Sylvain Berneron as a true visionary and a generational talent.  The Quantième applies Berneron’s virtuosic technicality to a watch that embraces a more traditional look than the Mir...

TAG Heuer’s Latest Monaco is an Impressive Achievement in Additive Manufacturing Worn & Wound

TAG Heuer’s Latest Monaco is an Impressive Achievement in Additive Manufacturing

Dubai Watch Week is upon us, and TAG Heuer is using it as a launching pad for for a new version of what is objectively one of the most impressive watches they’ve ever made. The Monaco Split-Seconds Chronograph Air 1 builds on the Monaco Split-Seconds that was introduced at Watches & Wonders in 2024. That one, you’ll recall, had a movement fashioned largely from titanium and weighed in at just 85 grams. The retail price at the time was a head scratching CHF 135,000, but it was also an incredibly impressive caliber and feat of engineering. Rattrapante chronographs like this are indeed quite rare, and certainly one with a caliber made of titanium is unheard of and adds additional layers of complexity to whole endeavor.  The new Air 1 version of the watch is still 85 grams, but it achieves that weight even with new solid gold components in the case. The design of the case, still in the iconic Monaco square, has been substantially reworked and inspired by design and manufacturing processes that are part of the Formula 1 landscape. The case has effectively been hollowed out, with intricately skeletonized case flanks designed to maximize the weight to performance ratio. TAG Heuer achieves this through a process they refer to as Selective Laser Melting (SLM). This is an additive manufacturing process that is typically applied in aerospace, medical, and automotive manufacturing, and like other forms of 3-D printing it’s essentially a cheat code in achieving otherwise impossi...

Hanhart and German Magazine Armbanduhren Unveil a Limited Edition Preventor HD12 in Purple Worn & Wound

Hanhart and German Magazine Armbanduhren Unveil a Limited Edition Preventor HD12 in Purple

I’ve long had a contentious relationship with the color purple; between youth softball teams and grad school alma maters, it’s always difficult to find anything to wear with the color that isn’t immediately clashing. But purple is also a color associated with luxury and royalty, so I am approaching the new Silk Purple Hanhart Preventor HD12, a collaboration with German watch magazine Armbanduhren, with an open mind.  Hanhart’s Preventor HD12 was originally launched in August 2024, and has fast become one of the Swiss-German brand’s most popular pieces. A field watch-style dial design paired with HD12 scratch-resistant steel, and powered by a Sellita caliber SW200-1 or Soprod SOP P024 automatic movement, the Preventor combines the vintage styling that Hanhart is known for with robust construction and durability.  With easy-wearing case dimensions of 39mm in diameter and 46mm lug-to-lug, the Preventor positions itself as an everyday timekeeping watch with few complications-even lacking a date window. The HD12 steel is made scratch-resistant through a multi-stage hardening process, in which carbon is diffused into the steel and the case is covered in an additional PVD coating. Hanhart continues to tout the “hardness” factor of the Preventor by protecting the dial with a scratch-resistant convex-curved sapphire crystal.  Of course, the dial is where the fun happens for this limited edition Preventor. The matte Silk Purple contrasts starkly with the white Ara...

Hands-On: Behrens and Vianney Halter Collaborate on the Impressive Master Collection “KWH” Limited Edition

Vianney Halter, the legendary independent watchmaker, has collaborated with Behrens, the Chinese indie that over the last few years has gradually upped the ante in terms of their watchmaking and their own ambitions in the international watch industry. The new watch, the Behrens Master Collection “KWH” Limited Edition, is sure to be one of the most talked about watches of Geneva Watch Days 2025, and should cement Behrens as a real player in the independent watch scene, while reintroducing Halter to a new generation of enthusiasts.  Collaborations within the indie watch world are frequent, so it’s worth spending a moment to contextualize the importance of Vianney Halter working with Behrens on this watch in particular. Halter is considered by many to be on the proverbial Mt. Rushmore of indie watchmakers who set the stage for the modern avant-garde watchmaking moment that we’re in the midst of. His Antiqua, a truly radical design upon its release, is still one of the most influential watches of its era, or any other. That he’s chosen to not just lend his name to a Behrens release but actually create an all new caliber for it feels like the strongest possible endorsement, and a signal that he and the young Chinese brand share a certain watchmaking philosophy.  The chief aesthetic inspiration behind the new piece is the square shape of antique electricity meters and the concept of “pixel nostalgia” (think video games like Snake and Tetris and you get the idea)....

Best Watches Under $10,000

Building a watch collection is generally a progression, beginning with the accumulation of a handful of modestly priced favorites and building toward the quest for pricier and more coveted models as one's knowledge and disposable income grow. We've showcased many worthwhile models in many price categories, but it's the sweet spot between $5,000 to about $10,000 that many consider the most fertile ground for finding some of those Holy Grails of timekeeping from some of the world's legendary watch brands. If you're in the market for your first "icon" watch (and you're looking to buy new rather than vintage or pre-owned), here are 21 of the best watches under $10,000 to consider, all topping out below the five-figure price barrier. Grand Seiko SBGM221 Price: $5,900 Reference:SBGM221, Case Size: 39.5mm, Case Height: 13.7mm, Lug Width: 19mm, Crystal: Sapphire, Water Resistance: 30 meters, Movement: GS 9S66 In 2017 Grand Seiko released the SBGM221 GMT which has stood as one of the brand’s best values to date. Inspired by some of their 1960s designs, the SBGM221 is characterized by that simple ivory-colored dial and vibrant blue GMT hand not to mention the eminently wearable 39.5mm wide steel case. And then there is the Zaratsu polishing throughout the case and dial which plays with the light in a way that only Grand Seiko seems able to do. The Caliber 9S66 is a tried and tested “true” GMT movement that allows you do independently adjust the hour hand and operates at 4 Hz w...

Catching Up on New Releases from Ming, Wren, Squale, and Doxa

Happy Saturday! Dive watch summer continues – we’ve noticed some fun new divers, all limited editions, come across the transom lately. New water ready releases from Doxa, Wren, and Doxa are profiled below. We’re also spotlight the latest from Ming – while not a diver, it has a stealthiness to it that feels appropriate for the season. Let us know in the comments what you think of these new releases, and what we might have missed. Wren Diver 38 Wren is back with their second watch, the all new Diver 38. The brand, founded by Wrist Enthusiast’s Craig Karger, launched last year with the Diver One, and the new piece is a scaled down, and perhaps more refined take on the original concept. The new version of the watch is smaller, coming in at, you guessed it, 38mm, and is just 10.7mm tall (the original was 41mm in diameter and over 13mm thick). The dial has a sandwich style design, in either a gradient seafoam green or aqua colorway. According to Karger, the goal here was to move Wren into a new category that “balances practicality, comfort, and refined execution.”  The Wren Diver 38 is available in date and no-date versions for $1,595. It runs on a ETA  2892 automatic caliber, and has 200 meters of water resistance. It’s mounted to a flat-link, stainless steel bracelet, and the ceramic bezel insert is fully lumed. Another nice touch: the rotor is skeletonized in the shape of a wren. More information on the Wren Diver 38 can be found on the Wren website here. Mi...

Rolex Oysterquartz: The Complete Guide

When Rolex introduced its Oyster Perpetual Land-Dweller watch at Watches & Wonders 2025, some longtime fans of the brand experienced a bit of déja vu for a Rolex watch - and a Rolex era - that have been largely consigned to the mists of history. Why? Because the Land-Dweller's angular case and integrated-bracelet design reminded many enthusiasts of the Oysterquartz models introduced during the early heyday of quartz watches in the 1970s. That's correct: once upon a time, Rolex, one of the undisputed champions of luxury watches with mechanical movements, jumped on board the Quartz Revolution bandwagon and not only produced its own in-house quartz calibers but marketed the watches that housed them as the pinnacle of the Crown's timepiece portfolio at the time. Here is everything you need to know about the Rolex Oysterquartz and its quirky but significant place in horological history.  Rolex Oysterquartz: The Early Days Of Electric Watches The wristwatch industry, like any other industry, is uber-competitive and every watchmaker wants to be the first to market with The Next Big Thing. In the 1950s and into the ‘60s, that Next Big Thing was a watch that could be powered by electricity. American companies like Hamilton, with the Ventura, and Bulova, with the Accutron, were among the pioneers, even though the movements that resulted from these early efforts proved to have difficulty maintaining reliability in mass production. The Japanese, particularly Seiko, took a diff...

Hands On: Patek Philippe Ref. 27000M Complicated Desk Clock

Patek Philippe’s Complicated Desk Clock Ref. 27000M-001 is the biggest release of Watches & Wonders 2025, with a footprint of 164.6 by 125 mm, and rising to 76.73 mm at its apex. Priced at an even CHF1 million before taxes, the clock is powered by a key-wound, 31-day movement – incorporating a one-second remontoir d’egalite – housed in a wedge-shaped sterling silver cabinet, decorated with green flinqué enamel. Initial thoughts While we’ve seen desk and table clocks from others in the space, none have been as incredibly high-effort as this. Patek Philippe claims the 912-part shaped caliber took seven years of development, including nine patent applications. That’s quite the investment in a product with limited mainstream appeal, and I find it reassuring that Patek Philippe is still willing to make those investments. The enamel work is enchanting and has precedent in early 20th-century silver travel clocks retailed by Cartier, among others. I could take or leave the baroque styling, but the dial and hidden “dashboard” look fantastic. I hope Patek Philippe will offer this movement in other styles down the road. If you’ve never experienced a key-winding watch or clock, it’s quite satisfying; I wouldn’t call it fun, but it’s not something you’re likely to get sick of. It’s an experience you can’t get with Patek Philippe’s other current production clocks, which use an electric motor to wind the movement without need of human intervention. The b...

[VIDEO] Hands-On: the Xeric Timeline Retrograde Worn & Wound

[VIDEO] Hands-On: the Xeric Timeline Retrograde

When I attended the New York Windup Watch Fair for the first time, I was exposed to a multitude of brands and had my eyes opened to just how unique the watch industry could really be. Among the brands that I was introduced to, Xeric stood out due to their futuristic, space themed and outright eccentric designs. As I’ve followed Xeric, they’ve continued down this same path, which brings us to the Timeline Retrograde. With this new release, Xeric has set out to revive the double retrograde movement, making it relevant and affordable for modern collectors. To do this, Xeric has introduced the “Xeric Caliber X5.1” movement: to put it simply, this is a custom built module which stacks upon a Miyota 9015, a common movement in the microbrand community known for its reliability and affordability. This module gets you a retrograde display without the exorbitant costs associated with developing an entirely new movement from scratch. Additionally, since the foundation of this watch is a 9015, it should prove to be a reliable timepiece for years to come, but also be serviceable in case something happens.  The standout feature of the Xeric Timeline Retrograde is, without a doubt, its retrograde time display. Unlike traditional analog dials where multiple hands simply rotate around the face, the two retrograde hands “sweep” across the dial in an arc and then jump back to the start. The hours are shown by a shorter hand that glides from 12 to 12, while the minutes are indica...

The Citizen Promaster Navihawk is Now Available in a New, Smaller Size

When it comes to “big” and “busy”, few do it better than the Citizen Promaster Navihawk. With a commanding presence packed with information, the aviation icon has always proven to be accessible in price, but not so much in size. That’s all changing, however, as Citizen unveils the 40mm Promaster Navihawk as part of their revamped Promaster Air collection.  Designed to favor legibility and functionality, the 40mm Navihawk will look familiar to those who know the larger model. It features a stainless steel case with satin finishing, polished accents, and a knurled crown, ringed by a rotating slide rule bezel. Inside the flat sapphire crystal, a complementary internal flange borders a metallic dial, available in three colors-khaki green, copper, and silver.  According to Citizen, the 40mm Navihawk features ⅕ second chronograph timing up to 60 minutes, and 12- and 24-hour time displays. Three black chronograph subdials take up the bottom half of the dial, and a rotated date indicator sits between the 4 and 5 indices. To balance out the date’s stilted location, printed details proclaiming the 200m water resistance and the Navihawk logo occupy the same location on the other side, between the 7 and 8 indices.  Inside, the 40mm Navihawk upholds the original model’s reputation of reliability and practicality. Citizen’s proprietary Caliber B620 Eco-Drive movement utilizes solar power to keep the watch running without use of a battery-very handy for those wit...
