OMEGA small seconds manual winding wristwatch. - Brand: OMEGA - Reference: 2900-1 - Caliber: 267 - Case Material: Stainless steel - Belt Material: Leather - Dial Type: Analog - Mechanical: Manual winding Ref. 2900-1 Cal. 267 The leather strap and buckle are generic. No accessories included. Case size: Approximately 34mm (excluding the crown) Case thickness: Approximately 9mm (including the crystal) Lug width: 18mm Currently running without any significant delay. The dial and hands have discoloration, stains, and clouding. The case has minor scratches and scuffs from use, but I don't think there are any noticeable large scratches or scuffs. The leather strap has hardened with age and shows signs of wear. I have carefully checked the operation, etc., before listing, but as this is an old model watch, there may be some age-related deterioration. Thank you for your understanding and purchase.
