This is a hand-wound wristwatch from AVALON. There are signs of aging such as scratches, scuffs, dirt, and deterioration. Since it has not been overhauled since I acquired it, I recommend an overhaul for actual use. Brand: AVALON Caliber: ETA cal.735 Case: Approximately 20.9mm x Approximately 41.5mm Lug width: Approximately 16mm Special notes: Time setting: Possible Winding: Possible On a flat surface, the daily rate appears to be +67 seconds.
