The watch runs when the caseback is off, but it stops when cased. The Mathey-Tissot Mechanical Wristwatch features a classic design with a polished gold case, white dial with Arabic numerals, and a brown leather strap with a buckle closure. This men's watch has a solid caseback and a fixed gold bezel, with a mechanical (manual) movement and a second hand. The round watch shape, analog display, and 12-hour dial make it a stylish and functional accessory for any occasion.
