Vintage Osco Aquatic 25 Jewels Shockproof Automatic Skin Diver. Germany, 1970s. Automatic movement, PUW 1461, 25 jewels. Date indicator, functional (no quick setting) Bidirectional rotating bezel. It features a stunning original black dial with perfectly matching original hands and tritium/lume indices that have aged to a gorgeous vintage patina. Stainless steel back, screwback case. Waterproof (NOT TESTED!!!) 38 mm in diameter without crown. The watch comes on a beautiful vintage steel bracelet that complements its look perfectly. It has a great aged character, though it is likely aftermarket (not original to the watch). The watch looks good for its age, but please keep in mind this is a vintage timekeeper that is at least 50 years old. It cannot look, perform, or keep time like a brand-new, modern quartz or mechanical watch. This is, first and foremost, a rare item intended for serious watch collectors. Shipping is from Romania, European Union. Thank you!
