Bernhard Lederer Central Impulse Chronometer*: A Superlative Watch But Is It Really A Chronometer?

According to Joshua Munchow, the Bernhard Lederer Central Impulse Chronometer is one of the most astounding pieces to be released in 2020, and when he first saw it on social media he actually gasped out loud. The more that he looked at it the more he fell in love with the style, the engineering, and the concept behind the movement. But he must ask: is it really a chronometer?

Hands On: Grand Seiko Spring Drive UFA Ushio 300 Diver SLGB025 and SLGB023

At Watches & Wonders, Grand Seiko launched its best dive watch yet, the Evolution 9 Spring Drive Ultra Fine Accuracy (UFA) Ushio 300 Diver SLGB023 and SLGB025. As a product, it is both shocking and obvious, combining everything Grand Seiko collectors have longed for: a moderately sized case, an improved bracelet and clasp, and a 300 m depth rating. It all comes packaged in a titanium case and an enthusiast-favourite no-date format, and retails for slightly less than Grand Seiko’s existing premium dive watches. It’s a strong statement from a brand looking to gain traction in the luxury sports watch segment. Initial thoughts Seiko’s dive watch pedigree is one of the strongest in the industry, from their iconic saturation divers of the late 1960s to the gone but not forgotten SKX. Yet the flagship Grand Seiko brand has struggled to field a compelling dive watch. Bulky cases, strange proportions, odd depth ratings, and clumsy clasps held back past offerings. Fortunately, Grand Seiko has finally overcome these shortcomings and can finally boast a highly competitive diver’s watch. I made a wishlist for Watches & Wonders 2026 not long ago, at the top of which was my vision for a Grand Seiko UFA Spring Drive diver. To be clear, I’d already known a dive watch using the new cal. 9RBx family of Spring Drive movements was coming based on trademark filings, but I wished for something that many Grand Seiko collectors have wanted for years – a moderately sized dive watch, wit...

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...

Serica Introduces The 5330 Dive Chronometer - The Brand’s First Watch To Feature A Date Window

The guys at Serica take their vintage-inspired designs very seriously. The brand’s watches are all about the perfect proportions, high legibility, and great wearability. Up until now, a date window wasn’t part of that equation. However, as representatives of many brands tell us, some people won’t buy a watch unless it has a date window.
