IWC Schaffhausen Old International Automatic This is a wristwatch from the 1970s. I've been collecting them, but I'm selling this one because my collection has grown too large. It was overhauled in 2023 and has been used occasionally since then. I don't have the receipt. It's an old watch, but I think it's in good condition. It keeps time well, and is running strong. It runs about 60 seconds fast per day when laid flat (varies depending on position). For antique watches, accuracy within 5 minutes per day is considered good. I've confirmed it runs for 24 hours. There's a small dent on the case back, but the crystal, dial, and case are clean with no noticeable scratches. The crown is in good condition, and setting the time is no problem. It has a fish crown. It has a hacking function. It is an original, not a redial. Movement: Cal. 8541B Case: Stainless steel Dial: Silver Case size: Approximately 36mm (excluding the crown) Lug width: Approximately 19mm Movement: Automatic Belt material: Synthetic leather (aftermarket) Please refrain from purchasing if you are looking for a perfect, like-new condition. Returns are not accepted to prevent swapping.
