eBay Finds: Great Vintage Watches from Zenith, Omega, Seiko, and More!

eBay Finds is back! This bi-weekly installment will feature a selection of watches currently listed on eBay that have caught the eye of editor Christoph McNeil (@vintagediver). If you come across any hidden gems on the ‘Bay drop us a note at info@wornandwound.com for potential inclusion. Zenith A3630 Vintage Diver  Here’s a rare gem to start us off this week, a vintage Zenith diver with original bracelet! This Zenith A3630 has a classically styled 38mm diver case in steel that looks to be unpolished. It does have some wear consistent with use and its age, but it does not look abused. The matte black dial looks excellent, with a contrasting white outer chapter ring and applied steel markers, and an unobtrusive date window at 4:30. The steel hands have large lume plots, and the hour hand has a nice big arrow tip for easy reading. The oversize crown is signed with the Zenith star symbol. The aluminum elapsed time bezel insert has some nice fading to it, but overall it’s in good shape. This piece comes with the original Gay Freres steel bracelet with a Zenith signed buckle. The Zenith automatic movement is clean and runs well per the seller. Great hard to find vintage diver! View auction here Heuer Autavia 1163 Vintage Chronograph  Next up is another heavy hitter, a vintage Heuer Autavia 1163 chronograph. Wow, this beast is a real beauty. The 42mm steel cushion case is superb, unpolished with crisp edges and the original brushed finish. The black dial looks original an...

Bring a Loupe: A Million Valjoux 72, An 18k Gold Constellation, And A Sarpaneva Moomin

Happy Friday again, Ballers, and congrats to whoever snagged the Omega 2998-4 on Goodwill earlier this week. I'm fighting multiple aspects of my nature—as a midwesterner and a dad—to avoid making lame jokes about the heat, but fingers crossed, the fever's breaking, and it'll return to average temperatures sometime soon for all of us. Scorekeeping last week's picks, the Hamilton sold for $4,300, the Speedmaster Soyuz for €18,000, and the Universal Genève Rattrapante for GBP 4,250 . The Goldpfiel Vianney Halter sold, but the auction house hasn't listed the price online and hasn't responded to my email, so we'll all have to live with the mystery. Strays I mentioned Always Sunny last week, and now this week there's this exquisite Movado Ermeto with a caseback dedication—Dennis from Mac—that feels too good not to include. I figured it'd be fun to stir the pot last week and argue the Hamilton Model 21 as the Most Important American Watch in history. For whatever it's worth, the runner-up would've been the Bulova Accutron, and the purest expression of that watch is the Spaceview, of which there's a nice (though non-running) version available here, which auction lot also includes a Spaceman watch (also not working), and the Spaceman, for what it's worth, deserves more oddball attention.  Photo courtesy of Seuyco. Here's an almost comically reserved but gorgeous Grand Seiko SBGW235, and, in the same auction, here's what sure seems to be a great example of an IWC 'Steril...

Seiko Unveils One-Off Cosmic Watch for Shohei Ohtani SJX Watches
Seiko Unveils One-Off Cosmic Watch Jul 3, 2026

Seiko Unveils One-Off Cosmic Watch for Shohei Ohtani

Seiko’s latest wristwatch is the surprising Star Time, which features a disc-based display that tells the time as well as elapsed time for up to one million hours, equivalent to 114 years. An unconventional and philosophical watch for a typically conservative brand, the Star Time is unfortunately not available commercially but is instead a unique creation for baseball superstar Shohei Ohtani. Japanese by birth but now a star in America’s Major League Baseball, where he plays for the Los Angeles Dodgers, Mr Ohtani is a longtime and loyal Seiko ambassador who first partnered with the watch brand in 2016, well before he was a global star. Though Seiko has unveiled limited edition models associated with the ballplayer in the past, the Star Time is the first unique watch made specifically for Mr Ohtani. Shohei Ohtani (left) and Seiko Watch Corporation Chairman and chief executive Shinji Hattori Initial thoughts The Star Time is a surprise coming from Seiko. Even though Seiko builds excellent watches across the breadth of the price spectrum – while keeping a keen eye on value – its watches are almost always predictable (though the concept watches from its annual Power Design Project are always intriguing but never commercially available). In contrast, the Star Time philosophical and impractical, with a simple yet complex display. Though the display is straightforward, the engineering behind the module that underpins the five discs is more complex than it might seem given...

Grand Seiko’s Evolution 9 Refresh Arrives - with Tapered Quick-Adjust Bracelets

The much-anticipated refresh of Grand Seiko’s Evolution 9 line has arrived with new bracelets for six existing dials, as well as a newcomer and a mid-sized version of the fan favorite Lake Suwa. This brings much improved bracelets to Grand Seiko’s upmarket (and very successful) Evolution 9 line, fueling Seiko’s global ambitions for its flagship luxury brand. Moonlit Lake Suwa (SLGB007) Initial thoughts If the UFA Ushio Diver launched earlier this year proved anything, it’s that Grand Seiko is listening to its customers, and those customers want slim watches, case back power reserve indicators, better bracelets, and a tool-less quick adjust clasp. The Evolution 9 line, launched six years ago in 2020, met half of these requirements, being let down by only the bracelet. With this refresh, the Evolution 9 becomes an even more competitive, and compelling, collection. Grand Seiko’s in-house quick-adjust clasp. Image – Seiko Watch Corporation Unfortunately, the changes also come with a significant movement downgrade for the Spring Drive models, replacing the extended power reserve cal. 9RA2 with the simplified cal. 9RB2. That said, the UFA designation will be seen as a significant upgrade to all but the nerdiest collectors, making it a coup for Grand Seiko as the new movement adds value for the customer while presumably being less expensive to manufacture.

Grand Seiko Announces a Major Refresh for the Evolution 9 Collection

Grand Seiko has announced a major refresh in their Evolution 9 collection across multiple metals and movements, and incorporating enthusiast favorite dial designs. A total of nine new watches have been announced as part of the update, and together they serve as what appears to be a new standard for Grand Seiko’s flagship collection. There’s a lot to chew on here, and depending on what interests you about Grand Seiko (or where you feel they have shortcomings) a number of different aspects of this update might be what draws you in. Everything they’ve announced, though, represents tangible improvement over what came before.  First, the news that many enthusiasts will probably zero in on immediately: Grand Seiko’s micro-adjustable clasp now appears to be standard. After introducing it last year in a limited fashion, there were plenty of gripes about backwards compatibility and options for the future. The message here seems to be that the more heavily tapered bracelet with micro-adjustment built into the clasp will be a regular feature across Evolution 9 watches. Importantly, for these releases, that applies to both 37mm and 40mm references.  Grand Seiko is also standardizing their premium alloys in steel and titanium in the Evolution 9 collection. Of the new watches introduced this week, the seven in steel are all in Grand Seiko’s Ever-Brilliant Steel alloy, which has a more lustrous shine and shows off Grand Seiko’s finishing more dramatically than standard stee...

Introducing: Grand Seiko Updates The Core Evolution 9 Collection With Tapered Bracelets And Micro-Adjustment Clasps (Live Pics)

What We Know Today, Grand Seiko introduces nine new variants to the three-hander, time-and-date models in its Evolution 9 collection. If you're feeling overwhelmed by that already, don't worry. Yes, there's quite a bit of nuance to unpack here among all these references, but not all nine are really new watches, per se. Many of them are existing models, just slightly modified. If you've read the title of this article, you'll already know that the biggest updates to these Evolution 9 models are things that collectors have long clamored for— tapered bracelets and clasps with tool-free microadjustment. Yes, for those who weren't able to achieve a perfect fit with previous Evolution 9 models, they will be able to now and can adjust accordingly, especially in hotter months with more wrist swelling. The clasp design comes from the original Evolution UFA SLGB003 model introduced last year, but now has spread to the rest of the collection, in both steel and titanium versions, and both 37mm and 40mm. Gone are the 5-day Spring Drive 9RA2 calibers used in the collection, replaced entirely with the U.F.A caliber 9RB2. This means that for those who found the 37mm U.F.A models too small, the more classic 40mm versions now get the ultra-accurate caliber that features an annual rated accuracy of +/- 20 seconds (timing per month is quoted at +/- 3 seconds). This is a big deal, and I think it suggests that Grand Seiko could be making a move to replace all of its Spring Drive calibers down ...

Seiko’s Latest is a Series of Silk Inspired Watches in the Presage Collection

When you think about it, silk is an absolutely fascinating material. Dating back thousands of years to Neolithic China, the labor-intensive process has produced one of the finest, softest materials produced by man. But what is it about that process that makes silk so unique and rare that people pay thousands of dollars for, say, a silk scarf? Well, to be honest, it’s probably not what you expected. You see, silk begins with silkworms being fed a diet of mulberry leaves. When they’re ready to enter their metamorphosis, the worms begin secreting a filamentous protein for their cocoon, which is then harvested, softened, spooled, and ultimately made into the fiber we consider a luxury. Pretty gross neat, huh? Well, it seems Seiko thinks so, too. The brand’s latest additions to the Presage Classic Series are inspired by Tomioka silk, a premium variety produced around the Tomioka Silk Mill in Gunma Prefecture. And while this is not the first time Seiko has used the Presage platform to honor Japanese craft, this might be one of the collection’s prettiest releases (in my humble opinion).  Looking first at the Tomioka Silk Promotion Organization Limited Edition, it’s easy to see the inspiration (and namesake for this particular reference) at first glance. Its white dial is finished with a pearl-like coating, while the rose gold-colored case and dark brown leather strap are inspired by the brick facade of the mill. The three additional models use the same silk-inspired di...
