Seiko Astron GPS Solar Dual-Time watch, silver/gray, SSH153J1
Silver-gray Seiko Astron GPS Solar Dual-Time watch with chronograph and titanium bracelet
The chronograph's 1/20-second subdial at 12 o'clock is new in this Seiko Astron watch. The subdial at 6 o'clock shows the time in a second time zone and works as a 12-hour counter when the chronograph is used. The silver-gray dial is surrounded by a black bezel made of ceramic and titanium. The sapphire crystal is double-curved, and the hands and indexes are luminous, so you can read the time even in low light.
The new 5x83 caliber receives the GPS time automatically twice a day. The titanium bracelet fits wrist sizes from 160 to 195 mm, and the clasp adjustment system lets you change the length with one press. Water resistance of 100 m / 10 atm is enough for swimming, water sports and snorkeling, but not for scuba diving. Astron is Seiko's collection of GPS Solar watches, in which the time zone and the precise time come from satellites.
