This is a genuine BROBA military watch from the time. It's a wristwatch manufactured and used as an official US Army issue item in the 1940s-50s. As per military watch specifications, Lug width: 16mm Size: 34mm (including the crown) These are representative sizes. Among military watches, whose value continues to rise year after year, this is a model that has become increasingly rare. A similar item was being sold on Rakuten Ichiba for approximately 75,000 yen, but it was unclear whether it had been overhauled. Since this watch is also being sold without an overhaul, the price has been significantly reduced. This is a famous and timeless design as a military watch. The black dial and simple appearance allow it to be worn universally, without regard to the clothing you wear. For this listing, an unused bracelet has been attached. This is a so-called bamboo bracelet (ladder bracelet), which cost about 3,000 yen. Once you get used to it, the fit is excellent, and the design can be worn year-round, making it a valuable item. Before listing, I wound the watch and confirmed that the small seconds hand was moving, but I have not precisely measured the daily rate. The seller wound the watch at 8 am and found that it was running with little deviation by 8 pm, and it was used without stress. Individual differences may occur due to posture, so please consider this as a reference only. This is a vintage item from approximately 70 years ago. Please refrain from purchasing if you do not understand vintage items or vintage military watches. Although it is running, please consider purchasing it with the assumption that it will be overhauled. Also, I am not an expert, and I cannot guarantee that the exterior and interior are completely original. Please understand this before considering a purchase. Unfortunately, counterfeit military watches are prevalent, so returns are not accepted to prevent swapping (as an aside, I have been targeted by swap scams twice in the past). For those who also love military watches, or those looking for a universally usable hand-wound watch, how about it? Thank you. ★
