eBay Finds: Three Great Vintage Seikos, a Few Cool LED Watches, and a Classic Omega Seamaster

eBay Finds is back! This bi-monthly 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. Seiko 7T27-7A20 Chronograph  Starting off this week with a beautiful vintage Seiko 7T27-7A20 military style quartz chronograph. This is the same model that was issued to the RAF, but without the military markings. You’ve got to love the clean looks of the black dial with black subdials and broad outer minute ring. The 38mm steel case looks clean and unpolished. The dial and hands are perfect. Seller states the watch runs and works as it should. This is a very popular model, and rightfully so. Great civilian version of a classic modern military watch. View auction here Vintage Omega Seamaster  This may not be your classic ‘fat lug’ 1950s Omega Seamaster, but it is still a fantastic watch. This late 1960s Seamaster has a larger, more modern case at about 40mm. The case is unpolished with nice sharp edges and the original brushed finish. The silver/champagne dial is original and looks perfect, with large applied steel baton markers and large steel hands that have both black and lume inlays. This model has a day/date window at 3 o’clock. The watch comes on what looks like the original Omega steel bracelet and it matches the style perfectly. No movement picture but the seller state...

Celebrating 80 Years Of Rolex Datejust With Fratello - Five Datejust Facts You (Probably) Did Not Know

The mighty Rolex Datejust turns 80 this year. That makes it one of the longest continually produced watches out there, which is no small feat. At Fratello, we intend to celebrate with a series of articles on the model, which I get to kick off today. I would like to start the celebrations with five […] Visit Celebrating 80 Years Of Rolex Datejust With Fratello - Five Datejust Facts You (Probably) Did Not Know to read the full article.

Insight: Breguet’s New Sympathique Clock and Natural Escapement

Breguet will very likely close its 250th anniversary this year with a bang: launching a 21st century Sympathique as a tribute to perhaps Abraham-Louis Breguet’s greatest invention, a clock that could autonomously wind, correct, and regulate a removable watch. While the brand has released no details, and there haven’t been any leaks, a series of patents gives us a peek at the new Sympathique. Notably, the patent drawings illustrate two possible companion watches: a 60 m water resistant Marine tourbillon and a Tradition. The latter is more interesting as it uses a novel form of Breguet’s échappement naturel, or natural escapement. We explain both the new Sympathique 2025 and the natural escapement using information gleaned from Breguet’s patents. Breguet Sympathique No. 1 by Francois-Paul Journe Initial Thoughts Three of the most historied names in the watch industry are celebrating anniversaries this year. Vacheron Constantin marked the occasion with Solaria, the most complicated wristwatch to date, while Audemars Piguet introduced an all-new Royal Oak Perpetual Calendar (and promises more to come in the fall). In comparison, Breguet has debuted the Classique Souscription and Tourbillon Sidéral so far, both of which are objectively good watches but feel underwhelming in technical terms. A new Sympathique, on the other hand, would be the ideal centrepiece for the brand’s anniversary collection, being visually impressive, an icon of the brand, and entirely unique ...

Grand Seiko Shunbun SBGA413 Review Teddy Baldassarre
Grand Seiko Jul 17, 2025

Grand Seiko Shunbun SBGA413 Review

Some watches become icons unexpectedly, and we would argue that no model better represents that idea than the Grand Seiko SBGA413 Shunbun – a watch that, on paper, should not even be an icon to begin with. So much of this watch’s ascension into the broader horological pantheon has to do with everything that GS does right in its process to create a watch from start to finish.  We know the brand for its vertical integration, its attention to detail, its mastery of the craft when it comes to dial design, case construction, and finishing. Not to mention how the brand has made it mark as the the name in movement accuracy. All of these aspects and more are on full display within and without the SBGA413. It is a masterclass in subtlety and craft, and one that is truly more than the sum of its parts. To understand the SBGA413, we must first understand the origin story.  Grand Seiko Shunbun Background In 2019, Grand Seiko unveiled four watches as U.S.-only exclusives in what it called its “Seasons” collection. Each watch employed the brand’s 62GS case concept (the brand’s first automatic watch), and two were mechanical while the other two utilized Grand Seiko’s Spring Drive technology. The Grand Seiko Shunbun SBGA413 represented the Spring season and did so visually via a unique dial with a hint of pink emblematic of the cherry blossoms in bloom at the start of the spring season. This subtle dial which only appears in certain lighting conditions was paired with an u...

Sinn 556 Review Teddy Baldassarre
Sinn Jul 17, 2025

Sinn 556 Review

Founded in 1961, Frankfurt, Germany-based Sinn is one of those watch brands that has a rich history to back it up, and continues to produce well-thought-out and reasonably priced watches, but has yet to be catapulted into the watch enthusiast spotlight that other brands have achieved. This, in my opinion, is something of a shame, but the hipster in me also likes to think that its lack of over-hype is also one of the brand’s strengths. While we over here at the Teddy team have given lots of (well-deserved) attention to the Sinn 104 ST, today, I’m going to give some more love to another equally deserving piece within the brand’s contemporary catalog: the Sinn 556 I.  One could argue that a no-nonsense black-dial watch is a dime a dozen. Pretty much every brand under the sun has one, if not several, to choose from. But unpacking and picking apart what immediately looks to be simple is a watch journalist's bread and butter after all, so it is quite literally my job to get down to the nitty gritty of the unique ways in which the Sinn 556 I is compelling, and, for those in the market, to break down the reasons why (or why not) it should be on your list of watches to consider. I will also argue that simplicity is often the easiest design element to mess up. How many times has one watch been thrown off by too much unnecessary text and branding, a date window that breaks up the dial’s overall harmony, or those little details that people free from watch obsession would easi...

Watch Scrolling: Great Photography, Hot Takes, and Some Watch Related Art

It’s been a minute, but Watch Scrolling, our occasional series where we highlight watch and gear related Instagram accounts we think are worth visiting, is back. Now more than ever, as the algorithm increasingly wants to show us things we might not actually want to see, it’s important to highlight the collectors, enthusiasts, and creators that are really worth a follow. We’ll try to bring you a ton of variety in Watch Scrolling, both big accounts with lots of followers you might be missing, and newer, smaller accounts that are still pretty niche.  We’d love to hear your suggestions for Instagram accounts to feature in this series. Drop them in the comments below, or head over to our Worn & Wound+ Slack channel and join the conversation there.  @justin_sowders_art  Justin recently made his Worn & Wound podcast debut at the Windup Watch Fair in Chicago. He was there to talk about the Citizen Aqualand, but as an artist he’s inspired by a variety of watches, and his IG is definitely worth a follow if you’re at all interested in seeing where abstract art and watches meet. His oil paintings of watches are incredibly evocative and have a very real sense of physical depth. They’re colorful, complex, and will almost certainly make you think of the visual impact of a watch in a new light.  @watchopinions Historically, I’ve been a bit allergic to anonymous bomb throwers on the internet. I love a hot-take and think people should proudly stand behind them! But there...

Casio Has a (Mini) MoonSwatch Moment with their Ring Watch

It’s counterintuitive, but one of the things I appreciate most about working in the watch industry is being reminded of my blind spots. The narrative is often that this community is small and tightly focused, and on some level that’s true, but I think more broadly speaking, the watch world is actually enormous, and there are large enthusiast communities we’ve barely tapped into. That became incredibly clear over the course of Windup weekend in Chicago as one of the most talked about watches of the show was not actually one that can be worn on the wrist. The Casio Ring Watch was not only the most diminutive timepiece of the weekend, but one of the toughest tickets at the event.   I was aware that these existed prior to Windup but I had no idea they were so sought after and collectible. A peek behind the curtain: as an authorized retailer for Casio, the Windup Watch Shop sells Casio and Casio G-SHOCK watches at the fair, so over the course of the weekend, through Slack messages, daily team meetings with my Shop colleagues, and conversations over quickly devoured lunches before heading back out to the show floor, I was able to get a sense of the demand for these things. Each day’s allotment essentially sold out in the fair’s early hours, and those who were able to grab one felt they walked away with the prize of the show.  The CRW-001 Casio Ring Watch has a retail price of $120, but a quick Google search reveals owners are asking anywhere from $160 to $200 for th...

Ulysse Nardin’s Blast Free Wheel Dressed in German Silver SJX Watches
Ulysse Nardin s Blast Free Wheel Jul 16, 2025

Ulysse Nardin’s Blast Free Wheel Dressed in German Silver

Ulysse Nardin presents a surprisingly striking new version of its most forward-thinking tourbillon, the Blast Free Wheel Maillechort. An interesting blend of classic finishing and bold, three-dimensional architecture, the limited edition piece is unlike the generally future-forward aesthetic pushed by Ulysse Nardin in recent years. The latest Blast Free Wheel retains the novel movement construction with elevated moving parts and a constant force mechanism integrated inside the tourbillon, but now set against a traditional, grained plate in maillechort, or German silver. Initial thoughts The Free Wheel is a long established collection, having been rolled out in several case styles over time, but this new incarnation is arguably the best one yet. The Le Locle-based brand is known for its overall loud designs and its tendency to push a very modernist look, so the old-school approach with maillechort is unexpected but appealing. The Blast Free Wheel still retains a somewhat loud case design, but the modernism here is more restrained and the futuristic movement is toned down by its finishing. As the name suggests, the main point is maillechort, a brass alloy better known as German silver. Long employed in historical watches, the material is usually associated with classic timepieces from the likes of A. Lange & Söhne or artisanal watchmakers, but here it compliments the avant-garde movement well. The soft silver-grey hue of the German silver serves as an excellent backdrop for...
