Couldn't load pickup availability
A refined neo-vintage Seiko Tank in near new old stock condition—a rare find that captures the understated elegance of Japanese dress watchmaking at its finest.
Case: Polished stainless steel with rose gold-tone accents in a classic rectangular tank design, clean lines and minimal wear, preserving its original factory finish.
Dial: Crisp white dial with applied Roman numeral markers and dauphine hands, exuding timeless sophistication.
Bracelet: Adjustable black leather strap that complements the watch's classic aesthetic.
Special Note: This watch is in near new old stock condition and features the rare S.W.U. markings. Most collectors interpret S.W.U. as a reference to Suwa Seikosha, one of Seiko's historic manufacturing divisions. Seiko historically had two competing factories—Suwa Seikosha and Daini Seikosha—that produced watches simultaneously to push innovation and hedge production risk.
Shipping: Free insured shipping within the United States. International shipping available; duties and taxes are collected during checkout and are the buyer's responsibility.
Returns: No refunds, only exchanges/store credit—vintage watches are not suitable for water or rough activities. They are durable as they have survived 30+ years of life but should be treated as such.

I am a huge fan of the watch it looks amazing and I can’t stop myself from looking at it when I’m wearing it. Super glad I found your account. The process was great as well, it is very cool to see new watches every week that are the same sort of vibe, I love the neo vintage style.

I recently purchased a Seiko Arc from Studio Demir. The process was super simple and I had my watch in less than a week. Hardest part of the whole process was just picking which watch I wanted, since all his time pieces are awesome!

Simple, sharp, and very wearable. This is the kind of watch that quietly looks good without trying too hard. A great everyday watch. Clean, timeless, and reliable. Not flashy, but that is exactly its strength. The kind of watch that works with almost any outfit and never feels out of place

I am such a big fan of Joshua’s work that I own several of his watches. Very very easy process overall, website is clear and always works fine, he is always available (if anything comes up) and the watches never disappoint. On top of that you get a bracelet that matches easily so many outfits and watches. 10/10.
