The Thomas Earnshaw Armstrong men's automatic watch features a round stainless steel case with mineral crystal and an exhibition case back. At 42 mm, it's the perfect size for any wrist, and its 50 m (165 feet) water resistance means you can wear it anywhere, even in the pool. The M-PTS-S01 movement with pull and push crown has a 38 hour power reserve, so you don't have to worry about winding it every day. The green dial is easy to read, and the silver stainless steel bracelet looks great with anything you're wearing. The deployment clasp keeps it securely on your wrist all day long.
