The Baume & Mercier Riviera automatic watch features a black steel case, rubber strap, sapphire crystal glass, and unidirectional rotating bezel. It has silver tone hands on an elegant black dial marked by index numerals for hours or Roman numerals optionally chosen from the list provided in Russian text but accurately reflecting available data points like "Silver tone hands" which might be a specific reference to markers or hour/minute indicators not clearly specified though Baumatic BM13-1975A movement is standard automatic caliber. The watch includes date functionality, scratch resistant sapphire crystal lens, round case shape measuring 42mm in diameter and approximately 10.66mm thick (about 5/8 inch), transparent screw-down case back allowing visibility of the inner workings including rotor details if applicable though not detailed here beyond generic automatic nature, powered by Caliber Baumatic BM13-1975A with a substantial 120 hours power reserve capability meaning it can run for about five days without winding or wearing. It is rated water resistant to 100 meters (around 330 feet) making it suitable for swimming but not scuba diving typically, and comes equipped with the manufacturer's comprehensive 2-year WatchMaxx warranty against defects.
