Seiko Astron GPS Solar watch, black titanium, SSJ015J1
Black titanium Seiko Astron GPS Solar watch with sapphire crystal and luminous details
Fully black titanium makes this Seiko Astron watch dark and light. Both the case and the bracelet are titanium, and the surfaces of the bezel are angular. The dial is black with a grid pattern. The curved sapphire crystal has an anti-reflective coating, and the luminous indexes and hands glow green in the dark.
Astron is Seiko's collection of GPS Solar watches, in which the time zone and the exact time are retrieved from satellites. You can update the time zone while traveling at the push of a button. The power comes from light, so the battery never needs replacing. Water resistance of 100 m / 10 atm is enough for swimming, water sports and snorkeling, but not for scuba diving. The case is 41.2 mm wide and 12 mm thick.
