Seiko SBXA003
Seiko SBXA003 Review | Customer Reviews | Check Prices
Similar to the other Seiko Astron watches, this watch’s timekeeping function is controlled by a GPS signal.
However, while some models make use of stainless steel in constructing the case and bracelet, the SBXA003 utilizes lightweight titanium. Prominently displayed against the black background of the dial are applied hour markers and sword-shaped hands.
A sub-dial situated at the 6 o’clock position serves as a 24-hour time display while a rectangular aperture at the 3 o’clock position indicates the date. Indicators for the power save and DST functions, as well as the signal reception result are found at the 10 clock position. The markings that border the edge, consisting of UTC hours and abbreviated city names, enable the wearer to determine the time in 39 other time zones around the world.
The dial is protected by a scratch-proof and anti-reflective sapphire crystal window, held in place by a black ceramic bezel.
