Seiko Astron Titanium GPS Watch

In their never-ending pursuit for the ultimate wristwatch, Seiko have created the Seiko Astron Titanium GPS Watch. As with all Astron watches it is solar powered and connects automatically to the GPS network. At the touch of a button, it adjusts to the local time anywhere on earth with a precision of 1/100,000th second, using just the power of light. Packed full of great features, this is no ordinary watch.

Titanium Case & Bracelet, Dial

Firstly, the watch has a 42.9mm titanium case with a super hard coating for durability. Similarly, the dual curved sapphire crystal also has a super clear coating. Secondly, the bracelet is also in titanium with a polished link running through the centre. Consequently, it is light and comfortable on the wrist. Additionally, it is perfect for anyone who has a metal allergy. The black dial is easy to read with applied hour indexes. A subsidiary dial indicates the day of the week with a smaller am/pm indicator positioned next to it. Furthermore, a second sub dial at 6 o’clock shows a dual time zone with a third dial indicating power reserve. Finally, the bezel is in black ceramic and displays world time across 39 major cities.


Equipped with a solar powered 5X53 calibre movement, the Seiko Astron Titanium GPS Watch has a perpetual calendar. It also benefits from automatic hand position alignment.

The Seiko Astron Titanium GPS Watch is an absolute must for anyone looking for a stylish, super accurate timepiece. The titanium case and bracelet make it light and comfortable to wear whilst the great features ensure you will always be precisely on time wherever you are. For complete peace of mind, it is also covered by a two year manufacturer’s warranty.
