Seiko Astron GPS Solar SSH159J1

A contemporary series thanks to its clean lines, slim profile, and, above all, compact, angular design that extends from the case to the bracelet and lugs. The SSH159J1 model is equipped with a 5X83 caliber with the new stopwatch function capable of measuring up to 1/20th of a second. Additionally, the time transfer function allows the hour and minute hands and the hand at 6 o'clock to move simultaneously, significantly reducing the time required to correct the time. The increased power reserve produces a high-quality dial with a high-contrast black and white texture. Finally, the high-quality textured titanium strap features a micro-adjustable buckle that allows for easy adjustment of the strap size.
