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...

Watches & Wonders: Grand Seiko Finally Gives Us a Medium Sized Dive Watch, and it Includes a Spring Drive Powered U.F.A. Movement
If you were take a poll of Grand Seiko enthusiasts and collectors to ask them what they thought was missing from the brand’s catalog, I have a feeling a significant portion of respondents would tell you the same thing: a great dive watch. Grand Seiko has, of course, been making divers for years, and a lot of them have been objectively outstanding and well liked by certain pockets of the Grand Seiko community. But they’ve never had a diver that’s really caught fire in the way that something like the Snowflake has – there’s no icon in their dive watch range. I think most would agree that this is at least in part because to this point the brand’s dive watches have always been on the chunky side, and not really a viable competitor to the Submariners and Seamasters of the world in terms of their wearability. Grand Seiko seeks to change that at Watches & Wonders this year, with the rather ambitious release of the new Spring Drive U.F.A. Ushio 300 Diver. This new 40.8mm High-Intensity Titanium dive watch uses a new Spring Drive movement featuring the same tech as last year’s 9RB2 Spring Drive caliber, which boasts an accuracy rate of plus or minus 20 seconds per year. There are really two notable things about this watch. First, there’s the movement, Caliber 9RB1, which has the same U.F.A (Ultra Fine Accuracy) designation as the 9RB2 introduced last year. The 20 second annual accuracy rate is, according to Grand Seiko, the most accurate wristwatch movement powe...

Omega Introduces a New Speedmaster Dark Side of the Moon Apollo 8 with a More Detailed Lunar Surface Inspired Dial and a Saturn V Seconds Hand
A January launch of a new Speedmaster (on a Tuesday, of course) has become a bit of a tradition for Omega over these past few years. Today, Omega has announced a new Dark Side of the Moon Speedmaster, which at first glance (and maybe a second and third glance) will look a whole lot like an earlier iteration of the popular ceramic version of the chronograph. The newest addition, though, has a few little updates that are likely to appeal to the most hardcore Speedmaster collectors. “Little” is the operative word here for at least one of them, which also might be the most technically impressive. The Speedmaster Dark Side of the Moon Apollo 8 is a follow up to the first edition of this watch, which was released in 2018 to mark the 50th anniversary of the mission. That original Apollo 8 watch was an immediate hit. It combined a lot of the modern tech and materials of contemporary ceramic Speedmasters with the familiar and highly regarded manually wound movement that is so much a part of the Speedy’s DNA. The rendition of the lunar surface on the dial was also particularly well executed and impressive. The new Apollo 8 features an updated movement, Calibre 3869, which is analogous to Calibre 1869 used in the previous version. This new movement has been specced to match Calibre 3861, the manually wound caliber at the heart of the current Moonwatch. It’s a significant upgrade from the older movement, and has been fitted with a co-axial escapement and meets all the requir...

Citizen Introduces All-New Automatic Caliber 0200
Having introduced the ultra-advanced quartz Caliber 0100 in 2019, Citizen is now turning to mechanical movements. Making its debut in the flagship The Citizen collection, the Caliber 0200 is a newly-developed automatic with all the technical features expected of a high-end modern movement, along with more elaborate decoration thanks to the input of Swiss movement specialist La Joux-Perret. Citizen’s first new mechanical since 2010, the Caliber 0200 elevates its mechanical watchmaking to a new level in both construction and aesthetics. Similarly, the first wristwatch equipped with the Caliber 0200 boasts a more sophisticated degree of finishing on its complex case and integrated bracelet. The Caliber 0200 Initial thoughts Going by the images, the Calibre 0200-equipped The Citizen is an impressive watch. And going by Citizen’s other high-end watches, this will almost surely look as good in real life as it does in photos. Measuring an elegant 40 mm by 10.9 mm, the case has complex surfaces and impeccable finishing, and also a distinctive look. Though some of the design elements do bring to mind other watches, it is original enough, which is a feat given the proliferation of integrated-bracelet designs today. But the highlight is the movement, which is perhaps best described as a high-end workhorse calibre. The construction and specs tick all the right boxes, and so does the finishing, which is superior to many watches – Swiss and Japanese – in the same price range. Th...
