Please understand that this is an old item. I purchased it about a year ago after it was overhauled at the time of purchase. The following information was provided at the time of purchase: Manufacturer: OMEGA Model: De Ville Country of Origin: Switzerland [Color] Exterior: Stainless steel Dial: White (lacquer) Size: 23mm (excluding crown) Length: 31mm Thickness: 6.5mm Lug width: 16mm Body material: Stainless steel Windshield material: Mineral glass Movement: Manual winding (mechanical) Cal.625 * The internal stay (resin) that holds the movement at the time was prone to hydrolysis and dissolving over time, so our shop used a 3D printer to create a separate stay using a non-dissolving resin. This was the description.
