The fourth collaboration between STI and CITIZEN. A lightweight full-titanium body and Eco-Drive technology put the power to keep going anywhere right on your wrist. The deep blue dial and carbon-look sub-dials bring out its sporty character.

The lightness of titanium
For the first time in an original STI watch, the case is made of Super Titanium™. At a remarkable 95 g, it keeps your wrist from tiring even during long hours of driving.

Design
The dial is finished in a mature, deep blue. The sub-dials carry a carbon-look print, edged with rings inspired by gold wheels. The second hand is painted in STI's signature cherry red.
The crown is engraved with the STI logo, with cherry red added as an accent.
Sapphire glass keeps the dial legible however the light falls while driving.
The STI logo sits at the centre of the case back, along with the serial number that marks it as a limited edition.
The bracelet clasp carries the STI logo and opens and closes with a single touch.

Technologies
Eco-Drive — light-powered charging. No battery changes are needed: even faint indoor light keeps it running, and a full charge lasts more than six months in complete darkness.
Duratect — CITIZEN's proprietary surface hardening treatment, protecting the case and bracelet and preserving their original beauty.
Radio-controlled — receives the standard time signal and automatically corrects the time and calendar across four world areas: Japan, China, the USA and Europe.
