Which Rolex Movement Takes The Top Spot? A Watchmaker’s Comparison Of Rolex Calibers 3135 And 3235, And Which Is Better? - Reprise

Ask any watchmaker about the Rolex 31 family of calibers and the story will be the same: it has stood the test of time. Ashton Tracy hasn’t met a single watchmaker who doesn’t love working on these workhorse Rolex movements. They are easy to service, keep great time, and stand up to abuse. Put simply: they work. So how does it stand up to big brother, Caliber 3235? Find out right here!

Introducing: The Zenith G.F.J. Calibre 135 Double Signed with Naoya Hida & Co

What We Know Today, Zenith introduces a new "Double Signed" program for its Calibre 135-powered G.F.J. collection, and its first entry in this series is a collaboration with a Japanese independent that might not require all that much introduction around these parts—Naoya Hida. The evolution of the G.F.J. line has not taken all that long, with its origins starting in 2022 with the Zenith Caliber 135 Observatoire Limited Edition, where ten Calibre 135 movements from the 50s were restored by Kari Voutilainen and introduced in watches done as a triple collaboration between Zenith, Voutilainen, and auction house Phillips. Just three years later, the Calibre 135 was revived as a modern caliber for a line called the G.F.J. (after Zenith's founder Georges Favre Jacot). In just a little over a year, we've seen three small runs of this watch introduced in different stone-dial and metal combinations—platinum with a lapis lazuli dial, tantalum with an onyx dial, and an upcoming yellow-gold GFJ with a bloodstone dial. In the meantime, this new Double Signed concept with Naoya Hida takes the G.F.J. in a very different visual direction. The hefty 39.15mm platinum case, with a thickness of 10.5mm and a compact lug-to-lug of 45.75mm, remains the same as other G.F.J. models. But that dial is unabashedly Naoya Hida, constructed out of solid silver with the distinctive hand engraving coming from the hand of master engraver Keisuke Kano, the man responsible for the hand engraving across al...

The Quintessential American-Made Watch Movement in a Smaller Case: Int

RGM Watch Company, named for the initials of its founder, independent watchmaker Roland G. Murphy, is the first American watch company to serially produce a mechanical watch movement since 1969 — the year that Lancaster, PA-based Hamilton pulled up stakes for its current HQ in Switzerland. Murphy, formerly Hamilton’s Technical Manager, founded his own eponymous company in Lancaster County, a historical hotbed of watchmaking, in 1992. His fledgling firm made the watch industry, and the worldwide watch-enthusiast community, take notice when it created, essentially from scratch, the groundbreaking Caliber 801 in 2007 —  a horological milestone that no other watchmaker in the United States had achieved in nearly 40 years.  Since then, Caliber 801 has come to define RGM’s distinctive and still very exclusive product family — the brand still makes only around 300 pieces annually — along with its dedication to classically vintage aesthetics, which evoke the bygone days when America reigned supreme as a watchmaking nation. Up until now, however, the smallest RGM watch you could get that housed the Caliber 801 movement, 90 percent of which is made in the U.S.A. and finished and assembled in Lancaster County, was 42mm — not huge, but still a bit intimidating for some would-be owners as case sizes continue to trend smaller. This week, RGM answers that constituency's prayers with the release of the Caliber 801/40 model, whose 40mm stainless steel case represents, accor...

Biver Debuts a Most Sophisticated Micro-Rotor Calibre

Founded by the namesake father and son duo, Biver has just debuted its second model, the Biver Automatique. Though a simple a time-only watch with central seconds, in contrast to the preceding Carillon Tourbillon, the Automatique is equipped with an elaborately executed movement that’s arguably the most impressive recent automatic. Besides decorative touches like guilloche on the bridges, the JCB-003 also features details like a grande sonnerie-style winding click. The calibre is paired with a comparably elaborately constructed dial with solid gold appliqués that’s available in a variety of materials, including mineral stone like Pietersite. The JCB-003 Initial thoughts The Automatique is clearly meant to showcase the brand’s ability to create a highly finished and refined time-only watch that can compete with more established producers, both in terms of the movement as well as habillage (namely the dial and case). The highlight of the Automatique is the JCB-003 movement. Developed in partnership with movement specialist Dubois Depraz, the JCB-003 is quite possibly the most refined micro rotor movement on the market today. Though it is functionally simple, the movement boasts decorative and technical details along with a high level of finishing. The over-engineered caliber is meant to serve as a base for future complications, which makes sense considering the high cost involved in constructing such a movement. Amongst the calibre’s notable details is the grande so...

J.N. Shapiro Launches the Resurgence, the First U.S. Made Mechanical Watch Since 1969

It’s not hyperbole to say that this is an historic day in American watchmaking history. J.N. Shapiro, the California based indie known primarily for their beautiful engine turned dials, has announced a new American made watch. According to the brand, this is the first mechanical watch that can be accurately described as “Made in America” since 1969, when the last American made Hamilton watches rolled off the production line. It’s a big deal, and a big step for a watchmaker that has been very much on the rise in recent years, taking on more complex production challenges with every new release. From dials, to cases, to movements, Shapiro can now claim a watch where virtually every component is made in a single workshop.  The watch, which Shapiro has dubbed the Resurgence, is the culmination of 12 years of learned experience among Shapiro and his team. At a glance, it has all of the aesthetic hallmarks of any Shapiro watch. A highly detailed multi level dial, for one, accented with intricate engine turning that has become Shapiro’s hallmark. What sets this watch apart, though, is the movement, which is not only beautiful to look at, with healthy doses of anglage, bridges with a distinct Damaskeening pattern (the American equivalent of Côtes de Genève), and rounded spokes on the caliber’s wheels, but has been designed and fabricated entirely in the United States. Shapiro produced his first movement prototypes in 2019, and that has led to the caliber at work in t...

Meet the New Seiko 5 Sports Field GMTs: The HDB001K1 and HDB002K1

The Seiko 5 Sports line has long been the gold standard for enthusiasts seeking a perfect blend of reliability, style and accessibility. Now, Seiko is elevating that reputation further with the release of the HDB001K1 and HDB002K1. Bringing the coveted GMT complication to the compact, rugged Field series for the first time, these timepieces are poised to become the ultimate daily-wear companions for travelers and adventurers alike.  A Design Built for the Real World Both the HDB001K1 and HDB002K1 honor the classic “trench watch” aesthetic that defined mid 20th century field timepieces. With a versatile 39.4mm case diameter, these watches offer a refined, manageable footprint that sits comfortably on almost any wrist.  The build is undeniably robust. Encased in high-quality stainless steel and featuring 100m water resistance, these watches are designed to handle everything from rainy commutes to light outdoor excursions. The aesthetic is tied together by a sophisticated five row stainless steel bracelet, which provides a premium feel that pairs just as well with a casual weekend outfit as it does with office attire. At the heart of both models is the Seiko Caliber 4R34, a reliable automatic movement that quickly became a fan favorite. A Tale of Two Dials Seiko is offering this rugged traveler in two highly textured, military-inspired colorways: The HDB001K1 “Khaki Drill” (Green) For those who want their watch to look like it belongs in an overgrown forest. I...

Unimatic’s Latest LE is a Modello Cinque Made in Collaboration with the Armoury

Considered one of the finest menswear retailers on the planet, The Armoury has been dressing men since its inception in 2010. Since then, it’s grown to become as much a store as a brand itself. Under the discerning eye of founder Mark Cho, every element of The Armoury is a considered approach to traditional, classic, and lasting style. It’s no wonder, then, that their latest release, in partnership with Italian brand UNIMATIC, would hold these same values. The UNIMATIC x The Armoury Modello Cinque U5S-TA ‘Blu Notte’ is a timepiece that balances classic design elements without ever veering into the fussy – while also being incredibly contemporary in its approach to creating a timepiece for today as well as tomorrow. Designed to be a daily wear watch, this watch has just enough design elements to keep the eye interested without veering into being ostentatious. For instance, the rich blue dial is a perfect neutral, while the concentric circles pressed into the dial give it a bit of depth. This is then offset against a cool grey seconds rail and dial trims, and all brought together with white hour and minute hands, filled with Super-LumiNova for visibility in a variety of conditions (like, say, cocktails in your best suit). The watch comes with a  ‘Blu Notte’ tapered quick-release two-piece TPU strap and a nylon strap is also included for more versatility.  Within the 36mm stainless steel case is an automatic caliber Sellita SW200-1b, promising approximately 41...

Delma Announces an Affordable Swiss Made Tourbillon to Celebrate their 100th Anniversary

Delma is celebrating its Centennial Anniversary in 2024. Family owned and operated in Lengnau, Switzerland, Delma watches has been in continuous production since its inception in 1924. To mark this tremendous milestone, they have created something quite special. Introducing the Delma 1924 Tourbillon. Yes, you read that correctly, a Tourbillon, limited to just 100 pieces. Historically, the Tourbillon complication has been reserved for ultra high-end watch brands to flex their horological muscles, while at the same time commanding equally high prices. In recent years, however, brands like Tag Heuer and Horage have brought these prices down to the realm of relative affordability. Delma wanted to do the same, while also making sure the movement was 100% Swiss. What is the big deal with Tourbillons? Simply put, the Tourbillon places the escapement and regulator within a rotating cage that revolves 360 degrees in 60 seconds, effectively negating any positional errors. Tourbillon calibers have a reputation for being rather delicate, and are often fitted to dress watches in precious metals. With the help of their Swiss supply partners, Delma has gone the extra mile to ensure these watches are shock resistant to 5000g and antimagnetic to 2000 gauss.  This sporty 41mm hand wound watch is made of 316L stainless steel and is nearly completely brushed, except for the beveled edges lining the top of the case. There is a display back, to admire the movement and it is fitted to a matchin...

J.N. Shapiro Debuts Entry-Level Infinity Series Pure

J.N. Shapiro’s Infinity Series Pure is a new entry point into the American brand. This follows the top-of-the-line Resurgence, the most American-made mechanical wristwatch built since Hamilton shut down in the 1960s. This new model focuses purely on the dial and hands, which are excellent, while trusting Swiss suppliers with ancillary details like the case and caliber. The result is a much more accessible, though less impressive, watch than J.N. Shapiro’s usual fare. Initial Thoughts When the original Infinity line was discontinued in 2023, it left the brand without an entry-level watch, and the company put all of its efforts behind the ambitious Resurgence project. Now that things have settled down, the team once again has the bandwidth to support a second model. The Infinity Series Pure uses an off-the-shelf La Joux-Perret (LJP) movement. While a good, slim movement with an extended power reserve, the LJP F200/7380 isn’t particularly premium, and a downgrade from the UWD cal. 33.1 used in previous infinity models. For example, Ralph Lauren uses the LJP movement in its Vintage 67 line priced at around US$3,000. The case is also outsourced, likely to a Swiss manufacturer, through the Alternative Horological Alliance (AHA), a consortium of independent brands that J.N. Shapiro helped found. This focuses all of Shapiro’s attention on the dial and hands, though both are significantly less complex than on the Resurgence. At US$26,000 the Infinity Series Pure is about a ...

Introducing - The New Hanhart Austrian Air Force AW169M Limited Edition

Hanhart was established in Switzerland in 1882 and relocated to Germany in 1902, positioning itself as a formidable competitor to the pricey Swiss-made stopwatches. It became successful by offering timing devices of comparable quality at a more accessible price point. A significant milestone occurred in 1938 with the development of the Caliber 40 mono-pusher chronograph […]

New: Panerai Luminor Due PAM01424 Burgundy

The Panerai Luminor Due was a collection which was first introduced in 2017, as the mid-sized, unisex Luminor model. The movement then was designated as the OP XXXIV which is assumed to have been renamed the P.900 caliber which is now found inside the new Due. The 42mm case Luminor Due bears the same crown guard as the iconic Luminor Marina, but with only 50m water resistance. Its slim profile and polished case is a marked stylistic variation from the original dive watch. The new dial color adds a nice statement to the hybrid classic timepiece.
