Helbros Antique Mechanical Wristwatch - Overhaul Required Size: Approximately 32mm without the crown This watch was sold for around 150,000 yen at an antique shop, but the crown is broken. You can wind it, so it can be used if you set the time to the stopped time, but the crown comes off when pulled out, so you can't set the time. The estimated cost for crown replacement and overhaul was about 40,000 yen, so this is the listed price. Please feel free to ask any questions.
