Vintage, made in Shanghai, China. A 17-jewel men's manual winding wristwatch. Brand name is ZUANSHI (meaning diamond). It has a simple, timeless design. Face size: Width including the crown: approx. 3.8cm Wrist circumference: up to approx. 19.5cm Please allow for some minor errors. There are minor scratches, scuffs, stains, and discoloration due to aging and use. I am selling it at this price considering its condition. The photos focus on noticeable scratches and stains, but there may be other scratches that are not visible in the images. Please understand this beforehand. Please refrain from purchasing if you are looking for a perfect item as this is a used item. The belt is unused, but it is an aftermarket product, so please consider it as a service. It is a manual winding watch. Please wind the crown to use it. It is in working order. The time is generally accurate. If you require more precision, please consider purchasing with the assumption of an overhaul. (Manual winding watches: I confirm the operation at the time of listing and shipping. Manual winding watches are not as precisely accurate as battery-powered watches. Please understand that there may be a time difference of a few minutes per day depending on the position, etc. I am listing items that I have judged to be generally accurate. Also, to reconfirm the condition of manual winding watches, it takes 2-3 days to ship. Thank you for your understanding.)
