SeikoSSH153J Astron Titanium Watch in Silver & White

Seiko presents the first Astron GPS Solar watch to combine Dual-Time technology with a chronograph function. With chronograph timing to 1/20th of a second, the new Calibre 5X83 boasts the highest performance in Astron's history. Thanks to the new movement design, this is the first Seiko Astron to have a sub-dial at the 12 o'clock position and allows the main dial and sub-dials to have contrasting colours and textures, creating a more dynamic and sporty presence. The watches feature a two-part bezel that includes an upper part in ceramic and a titanium frame. 

The hour, minute, and seconds hands, in addition to the three-dimensional indexes, are all filled with Lumibrite, enhancing legibility in low-light conditions. Thanks to the low center of gravity of the titanium case and the dual-curved sapphire crystal glass with super-clear coating, the watches ensure high levels of comfort and legibility. By connecting to the GPS network, the Astron adjusts at the touch of a button to your time zone and, by taking all the energy it needs from light alone and never needs a battery change.
