Weekend watch spotting with JR: #3

This weekend, I wore my DOXA SUB 200 130th Anniversary and went out in search of what other like-minded individuals had decided to attach to their wrist, and this is what I found out in the wild: Kosta’s Grand Seiko 9F quartz GMT SBGN005 Kosta’s passion for timepieces is still very much in its infancy … ContinuedThe post Weekend watch spotting with JR: #3 appeared first on Time+Tide Watches.

Photo Report: Assembling Caliber 9SA4 at the Grand Seiko Boutique

I’ve always had a fascination for peeking behind the curtain. Whether it was tearing apart broken electronics, rebuilding car engines, or opening the caseback of my first Seiko, I’ve always wanted to see and know how things work. As I’ve gone deeper into the horology rabbit hole, I’ve become more interested in the physical process of assembling a movement. While I can watch any number of YouTube videos, there’s something special about seeing it done in person, especially when you get to watch a Grand Seiko Watchmaker at work. Last week, I was invited to Grand Seiko’s boutique for a live assembly of their new 9SA4 movement, a high-beat, manually wound high frequency movement featuring Grand Seiko’s proprietary dual impulse escapement and 80 hours of power reserve. If you’d like to learn more about the 9SA4 and how it was created from the 9SA5, Zach Kazan covers that in detail here. This event was hosted at Grand Seiko’s Madison Avenue boutique (we celebrated the grand opening of this boutique in March, click here for the recap article) which features a gorgeous open concept main level, and an intimate lower level they’ve dubbed “The Cellar”. Unlike any cellar I’ve ever been in, this lower level features multiple lounge spaces, a full bar, a dedicated presentation space and, of course, plenty of watches. You’ll also find various items of cultural significance from the towns surrounding the Grand Seiko Studio Shizukuishi, which inspire the design o...

Citizen Combines Japanese Paper Dials and Cutting-Edge Quartz SJX Watches
Grand Seiko 9F movement Feb 3, 2022

Citizen Combines Japanese Paper Dials and Cutting-Edge Quartz

Long available only to the Japanese domestic market, Citizen’s top-of-the-line quartz watches have been slowly making their way into foreign countries in recent years (although last year’s high-end mechanical Caliber 0200 was launched internationally). The latest high-end quartz model, however, is being launched globally. The Citizen Iconic Nature Collection is a quartet of lightweight titanium watches featuring dials made of traditional, translucent Japanese paper dyed in vivid, natural colours. But the mechanics are cutting edge in contrast – a solar-powered quartz movement accurate to within five seconds a year. Initial thoughts Citizen’s ultra-accurate quartz watches are largely unknown outside of Japan, but that is gradually changing with the global rollout of new models, which are crucially dressed in eye-catching colours instead of the muted dials historically found on these watches. Citizen has used washi for dials on The Citizen before, but usually in a low-key white. The new Iconic Nature quartet calls to mind high-end quartz watches from Citizen’s Japanese rival, though Citizen’s offering edges ahead, at least on paper. The solar-powered A060 inside the Iconic Nature is accurate to +/- 5 seconds per year, while the Grand Seiko 9F movement is rated to +/- 10 seconds per year. And the practicality of the A060 is boosted by a perpetual calendar as well as an “on-demand” power reserve indicator. The price tag of US$3,500 is might seem high for an...

Ruby Resonance from Armin Strom SJX Watches
F.P. Journe Mar 2, 2026

Ruby Resonance from Armin Strom

Independent watchmaker Armin Strom has upgraded its flagship complication with a precious stone dial. The Mirrored Force Resonance Ruby is a five-piece limited edition with a dial cut from natural ruby. Initial thoughts Armin Strom is arguably the second-most prominent watchmaker (after F.P. Journe) to successfully bring “resonance” watches to market. We extensively covered the subject of coupled oscillator watches recently, which examines Armin Strom’s unique approach to achieving this mysterious effect.  Within this narrow niche, Armin Strom’s Mirrored Force series is certainly the broadest collection of resonance watches on the market, with multiple movements and many variations exploiting the almost magic coupling between two sprung balances. This new limited edition employs the familiar in-house caliber ARF21, which connects the two hairspring by a long, swivelling blade spring - dubbed the Resonance Clutch Spring. While the movement is certainly well known, this particular iteration of the watch is quite surprising: a thin slice of natural ruby serves as the dial, with all the imperfections and liveliness of a natural mineral.  Using a ruby dial is not only aesthetically appealing but poetic for a mechanical watch. The jewels serving as bearings inside every movement are synthetic rubies - a fancy sort of industrial mineral glass. The uneven bright pink and violet shades of the Mirrored Force Resonance Ruby’s dial assure us there is nothing artificial...

It’s M.A.D. 1 Raffle Time Again, Now with a New Green Version Worn & Wound

It’s M.A.D. 1 Raffle Time Again, Now with a New Green Version

If you’ve been trying to score a M.A.D. 1 – the absolutely insane, value oriented limited edition watch that most certainly is not an MB&F; but is conceived by many of the same people – you’re in luck. Max Busser, the “MB” of MB&F;, has announced that a new version of the M.A.D. 1 is soon to be released, this time in green, with options to purchase still determined by a raffle. Ever since the original M.A.D. 1 appeared in the spring of 2022, it’s been an object of considerable fascination for the many admirers of MB&F; who simply can’t afford a watch with a six figure price tag. The conceit of the M.A.D. 1 is that it offers a whole lot of the imagination and playful whimsy of an MB&F; piece, but with an off-the-shelf movement (heavily modified) in an unusual case for not a whole lot of money. Their scarcity, and the sheer visual impression these watches leave, has made them an enduring Instagram hit with a certain type of enthusiast.  The new M.A.D. 1 is effectively the same watch as the previous version, but with bright green accents instead of red. For those who might be brand new to the concept, a quick overview of how thing works might be in order. The heart of the M.A.D. 1 is a simple Miyota automatic caliber that has been inverted, so the back of the movement points up, where you’d normally find a dial. But there is no dial – just a rapidly spinning, triple blade, tungstend/titanium rotor, which we suspect is the single most heavily modified piece of...

Venezianico Introduces the Redentore Utopia, Featuring the Italian Made V5000 Caliber Worn & Wound
Venezianico Introduces Jun 13, 2025

Venezianico Introduces the Redentore Utopia, Featuring the Italian Made V5000 Caliber

It tends to be a big deal when a watchmaker unveils their first “in-house” movement, a pivotal milestone that often marks a step into the upmarket. For Italian brand Venezianico, tapping into the expertise of Fausto Berizzi, the technical director of OISA, was the key to their first proprietary mechanical caliber, designed, registered, and built entirely in Italy. The result is the Redentore Utopia, and its beating heart: the V5000 Caliber mechanical movement.  In a break from convention, the Redentore Utopia is more of a stage for the V5000 Caliber movement-a catalyst for the Venezianico brand and its future momentum. Still, Venezianico matches the enthusiasm of the movement with a visually-gripping timepiece that certainly doesn’t signal its status as simply a vessel for the brand’s technical growth. Wearing a 316L stainless steel case that measures at 38mm in diameter and 8.9mm in thickness, the Utopia is firmly a dress watch. The deep blue dial is constructed via ion plating and features a dazzling, hand-engraved guilloché pattern, designed exclusively for the Utopia on a rose engine lathe by master artisan Riccarfo Renzetti. The result is a radial motif that gives the appearance of being in constant motion, with light glancing off each angle as the watch is shifted on the wrist.  On the dial, baton-style, hand-applied indices line the circumference, and faceted alpha hands match the stainless steel case’s polished finish. The sole text detail on the dia...

Grand Seiko Introduces the 44GS 55th Anniversary Specially-Adjusted 9F Quartz

Long a leading player in the arena of high-end quartz watches, Grand Seiko’s flagship offering is the 9F quartz movement that is built with an attention to detail comparable to that of its mechanical calibres. Beyond the almost-artisanal production, 9F movements are all about accuracy – the standard movements are rated to within 10 seconds a year. Now Grand Seiko a limited edition equipped with a specially-adjusted 9F calibre, the Heritage Collection 44GS 55th Anniversary SBGP017 “Blue Clouds”. Signified by the star emblem on the dial, the movement within is regulated to run within five seconds a year – an average of less than a half second deviation a month. Initial thoughts Watches with colourful, textured dials are almost the norm at Grand Seiko, which has rolled out enough limited editions that such watches seem almost more common than their plain dial counterparts. The SBGP017 dial has a familiar texture, so at first glance it seems like yet another Grand Seiko limited edition. But a closer look reveals the fact that the SBGP017 is unusual. For one, it’s quartz. Grand Seiko quartz watches rarely have patterned dials and when they do, the dials typically have motifs made up of repeating symbols. In contrast, the abstract pattern found on the SBGP017 is similar to that found on Grand Seiko’s mechanical and Spring Drive models. Put another way, the SBGP017 is an atypical Grand Seiko limited edition because it’s quartz but has the aesthetic of a me...

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

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...

HANDS-ON: High-end quartz -  Grand Seiko celebrates the 25th anniversary of the 9F with two limited editions (SBGT241 and SBGV238)

If you’re a regular reader, I’m willing to bet that your views around quartz timekeeping will be pretty negative. After all, this is a technology that was (almost) responsible for the downfall of mechanical watches. But, as you’re about to find out, not all quartz watches were created equal. Sure, there’s the cheap and cheerful … ContinuedThe post HANDS-ON: High-end quartz – Grand Seiko celebrates the 25th anniversary of the 9F with two limited editions (SBGT241 and SBGV238) appeared first on Time+Tide Watches.

[VIDEO] Grand Seiko Redefines Accuracy - Again: Introducing the 9RB2 U.F.A. Spring Drive Caliber

2022: the Kodo constant force tourbillon. 2023: the Tentagraph hi-beat mechanical chronograph. 2024: the 9SA4 manual wound, hi-beat, dual-impulse escapement caliber, and Kodo Daybreak. It’s easy to forget that Grand Seiko has brought the proverbial heat to Watches & Wonders every year since the fair started, unveiling something that one could call “revolutionary” for the brand, if on varying scales. Well, it’s looking like 2025 will continue the trend with the introduction of Spring Drive Caliber 9RB2, the first caliber with U.F.A., or Ultra Fine Accuracy, designation. Before proceeding, there are two important concepts to understand: Spring Drive and Grand Seiko’s history with acronyms (which, if you know, feel free to jump two paragraphs ahead). Starting with the former, the elevator pitch, which I will take from our article dedicated to the topic is “Spring Drive combines the best of mechanical watchmaking and the best of quartz timekeeping to create a state-of-the-art caliber that lacks the weaknesses inherent to both of these movements.” A bit deeper, Spring Drive movements use the energy stored in a traditional mainspring to drive their proprietary “Tri-synchro” regulator, which replaces the classic lever escapement. It consists of a glide wheel, the rate of which is controlled by an electromagnetic brake, and is essentially regulated by an integrated circuit with a quartz oscillator. The result is a mechanical movement with quartz-like accuracy and...
