This is a hand-wound wristwatch by NITELLA. There are scratches, scuffs, stains, and deterioration due to age. Since it has not been overhauled since I acquired it, I recommend an overhaul for actual use. Brand: NITELLA Caliber: Unknown Case: Approximately 38.6mm x Approximately 22.2mm Lug width: Approximately 16mm Special notes: Time setting: Possible Winding: Possible On a flat surface, the daily rate appears to be +67 seconds.
