This is a hand-wound mechanical watch from EBERHARD. It's likely a model 31031, made in the 90s. It's a three-hand watch, but the largest hand is the seconds hand. I purchased it about two years ago from a used jewelry store in Tokyo, and while it was stated to have been overhauled, the accuracy is not guaranteed. It's old, so there are scratches overall. The strap is aftermarket. Please confirm the condition in the photos and only purchase if you understand.
