Break Through to a New Future.
A new design for the Seiko GPS Solar 5X83 Dual-Time Chronograph

Sophisticated and modern design
The latest designs are as advanced as the technology within. The watch is light and comfortable thanks to a case and bracelet made of robust and scratch-resistant titanium, which is 40% lighter than steel. A super-hard coating keeps the surface pristine and free of scratches, and the watch is water resistant to 10 bar.

A dial that imparts a sense of strength
The dial's vertical hairline finish gives the design a strong and solid quality.
