[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...

If 100 people were asked about the first words that come to mind when “Audemars Piguet” is spoken, I wager that almost all would respond with “Royal Oak.” That signals how popular Gérald Genta’s groundbreaking 1972 design has become. However, before this and even after the Royal Oak was released, Audemars offered a very different […] Visit In-Depth: The Audemars Piguet 5043BC “Ultra-Thin” And Caliber 2003 to read the full article.

Up Close: Citizen Caliber 0210 “The Citizen”
Citizen launched its flagship mechanical watch, the Caliber 0200, two years ago. Despite being better known for high-end quartz watches – including the most accurate ever – the Japanese watchmaker managed an impressively executed three-handed sports watch, with an equally outstanding new movement. Now the model finally receives a mechanical upgrade with the Caliber 0210, which incorporates a date along with subtle improvements to the external design, while retaining the excellent case and bracelet that define the model. Initial thoughts The Caliber 0210 indicates the brand’s interest in further developing this excellent model – encouraging for fans of the model like myself. Despite the Caliber 0210 looking much like its predecessor, it is actually a substantially different watch in tangible terms. Ordinarily the addition of a date would be a no-no for a purist enthusiast, but here the date is integrated well in terms of dial proportions and (re)design. The appealing attributes of the Caliber 0200, and now the Caliber 0210, clearly mark the two out as watches conceived for a niche audience, namely enthusiasts who appreciate quality – and are able to distinguish this from the competition (Grand Seiko to state the obvious). However, this target audience often prefers the purity of a three-hand watch without a date. At the same time, this audience comprehends the substantive upgrades in the Caliber 0210 beyond the date – amongst them the improved case constructi...

Seiko Brings the 6R54 GMT Caliber to the Alpinist Family
Seiko introduced a new caliber back in March via their Prospex GMT Diver collection, adding caller GMT functionality into the brand’s well understood contemporary dive watch platform. Those watches have generated quite a bit of chatter in the watch community, with many singing their praises with respect to overall fit, finish, and wearability, and others wishing for a more functional flyer GMT complication. While the dust might still be settling, Seiko marches on, with the latest crop of watches to feature their still new 6R54 GMT movement. This time, Seiko brings the movement to the Alpinist family, which seems like a natural place for a GMT equipped watch to land. It takes what has always been cast as an explorer’s watch (with its signature compass bezel) and gives it a modern, practical, mechanical complication for a different kind of exploration. I’ve always been a pretty big fan of the Alpinist for many of the reasons Blake identifies in his Missed Review. There’s something charmingly anachronistic about wearing a watch designed with such an old fashioned aesthetic (those cathedral hands, especially) but built to modern sports watch standards. With a GMT complication added, the Alpinist retains a lot (maybe all) of that old fashioned charm, just slightly tweaked. The Explorer-style steel 24 hour bezel gives these watches a clean and sporty look, and we still get the trademark handset and those big numerals (just at the cardinal positions here, rather than ev...

Citizen Introduces the Caliber 0200 “Japanese Armor”
A year ago, Citizen debuted its first all new, high-end mechanical watch in decades, The Citizen Caliber 0200. A wristwatch par excellence, the Caliber 0200 was so good that it was one of our tops watches of 2021. Now Citizen is following up with the Caliber 0200 “Japanese Armour”, the first limited edition of the model that’s available globally. Topped with a black ceramic bezel and textured dial, the samurai-inspired Caliber 0200 has a low-key aesthetic that still distinguishes it from the all-steel models. Initial thoughts Even though production hasn’t yet caught up with demand – there’s still a waiting list for the watch – the Caliber 0200 is still a niche product, just because it is a high-end, mechanical offering from a brand better known for its solar-powered or quartz watches, and mostly affordable ones at that. So a limited edition makes sense, since the small run will boost desirability and create buzz worldwide (Citizen did launch a 50-piece limited edition last year that was sold only in Japan). That said, the new edition is still very much a restrained design that’s almost monochromatic. It’ll be one of those watches that are recognised only by those in the know. Interestingly, both the new limited edition and the standard model stick to the same palette – grey, silver, and black – with the difference between the two being the quantity and intensity of each colour. On the limited edition, black becomes the dominant colour thanks to the ...

Omega Introduces the Speedmaster Moonwatch 321 “Ed White”
Having dropped enough hints – first the movement and then the platinum Speedmaster – that the launch is no longer a surprise, Omega has finally unveiled the watch many have been waiting for: the Speedmaster Moonwatch 321 in steel, a remake of the Speedmaster “Ed White”. Notably, the latest remake means that Omega now has a remake hall of fame, having reproduced almost all of the historically significant vintage Speedmaster models, namely the ref. 2915, ref. 2998, ref. 105.012 (sort of), the ref. 145.022 in 18k gold, and now, the ref. 105.003 “Ed White”. Worn by astronaut Ed White in 1965 when he became the first American to accomplish a space walk, during the Gemini 4 mission, the Speedmaster ST 105.003 has since been nicknamed after White, who unfortunately died not long after when a fire consumed the cabin of the Apollo 1 spacecraft in 1967. Reproduced faithfully Distinguished by its straight lugs, the “Ed White” has been replicated in fine form with the new Moonwatch 321. Omega gets an A for execution with the remake, though its score for creativity won’t be quite as high. The new Speedmaster is a dead ringer for the original, but executed in modern materials – plus faux-vintage Super-Luminova, naturally. Details exactly as on the original include the applied Omega logo and stepped dial The bezel insert, for instance, is a “dot over 90” like the original, but is rendered in robust ceramic with white enamel tachymetric markings, instead of the fra...
