1963 Chinese Air Force Aviation Watch Replica, a hand-wound chronograph watch. I've wound it and looked at it on my wrist, but I haven't worn it outside, so there are a few scratches on the case, but overall it's in very good condition. The sapphire crystal is also clean. It's currently running, and all functions, such as winding the mainspring by the crown, setting the time, and the chronograph function, work perfectly. It's probably a Seagull movement, so it should be reliable. The storage case and replacement straps, etc., the original accessories, are all included. The original NATO strap was cheap, so I've replaced it with an aftermarket NATO strap, which I'll also include. I purchased it in July 2025, so it's still in good condition. - Brand: Seakoss - Style: Chronograph - Material: Stainless Steel/Nylon - Dial Type: Analog - Case Diameter: 38mm - Lug Width: 18mm - Water Resistance: 50m - Crystal: Sapphire Crystal - Movement: Hand-wound
