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.

Which 1,000m-Rated Dive Watch Is Right For You? - Part II

When we published the first part of this exploration into 1,000m-rated dive watches, the response was immediate and enthusiastic. That didn’t surprise me. Watches capable of surviving a kilometer beneath the surface occupy a fascinating niche. They go well beyond everyday practicality and venture into the realm of over-engineering, professional utility, and, often, obsession. These […] Visit Which 1,000m-Rated Dive Watch Is Right For You? - Part II to read the full article.

Industry News - The COSC Releases Excellence Chronometer, its New, Stricter Standard in Chronometry

What is a chronometer…? In short, it is a watch that has been officially tested for its precision. And to guarantee the precision of watches, several tools exist, such as the ISO 3159 standard (which celebrates its 50th anniversary this year) and official organisations, such as the Observatoire de Besançon in France, the Glashütte Observatory […]

Introducing: The Héron Marinor - An Updated Dive Watch From Canada

Admittedly, we don’t hear about Canada much when it comes to watches. That’s a shame and perhaps slightly surprising, as it’s a large country with a variety of landscapes. Plus, there’s coastline and inland water to explore. This makes Montreal-based Héron a bit of an upstart. The brand began delivering watches in 2021, and its […] Visit Introducing: The Héron Marinor - An Updated Dive Watch From Canada to read the full article.

VPC Introduces the Type 39VM, an Uncommonly Thin Dive Watch Worn & Wound

VPC Introduces the Type 39VM, an Uncommonly Thin Dive Watch

Regular readers might remember our coverage of the debut watch from VPC almost two years ago. This was a special project as it comes from Thomas van Straaten, whose byline many of you may have seen over at his main gig, as a writer at Fratello. The Type 37HW, the debut release from VPC, was conceived as something as the ultimate enthusiast’s watch, with special attention paid to the small details that serious watch lovers are particularly attuned to. In practice, that means you end up with a watch that is very subtle, with lots of things that are special about it but perhaps don’t advertise themselves in big bold colors. VPC, after all, is an acronym for a Latin phrase that translates to “beauty through restraint,” and if that isn’t a mission statement of enthusiast focused watch culture, I don’t know what is.  For the second VPC release, the brand is back with a watch that builds on the design language of the Type 37HW but shifts it specifically into the realm of the dive watch. The Type 39VM is, according to the brand, the thinnest 200 meter water resistant automatic dive watch on the market, which is a bold claim but seems to be backed up by a cursory review of the data. The case height is listed at 9.34mm, which is quite thin indeed for a watch like this. In keeping with VPC’s design principles, van Stratten set out to create a watch that was purely functional but also didn’t sacrifice ergonomics or aesthetics. Through an exploration of figuring out wh...

Which 1,000m-Rated Dive Watch Is Right For You?

When you talk about dive watches rated for the sort of depths only a handful of human divers - let alone cameras, regulators, or submersibles - will ever see, you cross the border from sporting gear into mechanical heroics. Dive watches are built to match these endeavors. In this article, I’ll explore five extraordinary timepieces […] Visit Which 1,000m-Rated Dive Watch Is Right For You? to read the full article.

Year in Review: Watch of the Year 2025 Worn & Wound

Year in Review: Watch of the Year 2025

Our annual Watch of the Year post is here, and as always it’s a celebration of the diversity and strength of the enthusiast community. There’s a little of everything represented here, from the platonic idea of the Seiko diver, to highly experimental and ultra-modern, to emerging microbrands offering incredible value. But it’s not just about the watches themselves – every year has individual watches that are successful in the ways that get them onto lists like these. It’s the way our team assesses them, and gets to the heart of what makes a watch great, or interesting, or challenging.  We hope you enjoy our roundup of our team’s favorite watches of 2025. Let us know yours in the comments below, and Happy New Year!  Christoph McNeill  For my Watch of the Year this year, I of course went with a Seiko. I know, no surprise there, but consistency is a good thing right? What can I say, I absolutely love Seiko. And I’m not just a homer, they really do put out killer stuff year after year. I nearly picked one of the amazing and beautiful Grand Seikos (the SLGW007 ‘birch’ dial), but I’ve written about the Grand Seikos a lot, and as stunning as they are, I’m a dive watch guy at heart and there is one Seiko diver that really blew me away this year. I’m talking about the Seiko Prospex Marinemaster SLA081 Limited Edition “Shinkai” diver. For brevity’s sake I’ll just refer to it as the Shinkai from here on out. The Shinkai diver is modeled after the OG ...

Introducing: The JB300 Poulpro - Jacques Bianchi’s Technical Dive Watch Evolves

The JB300 Poulpro arrives as Jacques Bianchi Marseille’s latest take on a serious dive watch. It pairs some of the frivolous style of the earlier JB200 Poulpro with a more technical, titanium-based platform. This isn’t about flash; it’s about refining a recognized design language into something even more purposeful. In dive watches, there’s a fine […] Visit Introducing: The JB300 Poulpro - Jacques Bianchi’s Technical Dive Watch Evolves to read the full article.

Seiko SPB149 Review: The Blue Dial Prospex Diver Teddy Baldassarre

Seiko SPB149 Review: The Blue Dial Prospex Diver

An outsized part of Seiko’s history is within its dive watch heritage, going all the way back to 1965 with the company's first dedicated diver, the 150-meter 62MAS, released as the 6217-8000, and later, its larger-crowned sibling, the 6217-8001. It was the beginning of a lineage that went on to include legendary references like the Willard, the Turtle, the Marinemaster, the Tuna, and the SKX, just to name a small assortment of them. Today, Seiko’s broad dive-watch lineup is well-known for its rugged dependability: from the entry-level Prospex models to the elevated Luxe variants like the Seiko SPB149, there’s a Seiko diver for every enthusiast. Seiko has paid tribute to the 62MAS design in the past with limited editions, but in the 2020s, the brand has seen a slew of regular-production, and short-lived models – like the SPB143, 239, and 149, which stand as the most faithful renderings of the 62MAS, characterized by the brand as the Prospex 1965 Heritage Diver’s Watch. Although this model family came with different dial variants at its 40.5mm case size, today, we’re going to showcase the discontinued SPB149 before looking at the current production SPB143 and other modern day options which continue the 62MAS legacy. We will go through the standard points of its case, wear, dial, and movement, and then share concluding remarks about its overall legacy in 2025.  Seiko SPB149 Context In Spring of 2020, Seiko dropped a quartet of watches - the SPB143, SPB145, SPB1...
