Vintage Baume & Mercier Square-Cased Watch

The item is a vintage rectangular or square-cased wristwatch, likely from the Baume & Mercier brand based on the additional context provided. The watch features a gold-toned case, which appears to be solid gold or gold-plated, exhibiting a polished finish with some visible surface wear consistent with age and use. The caseback is a solid, unadorned gold-colored panel. Based on the visible engraving or stamping, there are text and numerical markings (e.g., '10260' and '385202') on the caseback which could denote a model number, serial number, or other manufacturing identifiers. These markings are somewhat faint but discernible. The watch is fitted with a dark brown leather strap with a textured, possibly alligator or lizard grain pattern, and a gold-toned buckle. The buckle matches the case in color and material. The strap shows significant signs of wear and age, including creasing, darkening, and possible stiffening. A small, dark cabochon crown is visible on the right side of the case, suggesting manual winding or time setting. The overall aesthetic points to a dress watch style, likely from the mid-20th century, possibly 1950s to 1970s. The condition of the case shows minor surface scratches and possibly some tarnishing or dulling of the gold finish, but no major dents or significant damage are observable from this angle. The strap, however, would likely need replacement for regular wear. The craftsmanship appears to be of good quality, typical of a reputable watchmaker like Baume & Mercier, even with the visible signs of age.
