Seiko Men's Astron Sports GPS Solar Watch SSE169J1

Built around Seiko's GPS Solar 8X53 calibre, the Seiko Men's Astron Sports GPS Solar Watch takes its power from light and its time from satellites. The 46.7 mm case is cut from titanium and paired with a rubber strap, a pairing built for long days on the move.

GPS time reception lets the watch set itself accurately wherever you land, while Daylight Saving Time adjustment handles seasonal clock changes without any fiddling at the crown. Solar charging means no routine battery changes. Water resistance of 20 ATM makes it suitable for swimming, snorkelling and water sports, and a 3-year international warranty is included.
