― ECB-S100 ―


A grille design inspired by automobiles

The dial design is inspired by a sports car’s grille.
The precise dial construction — the combination of the metallic mesh, the X-shaped metal part,
and the dial ring with its index marks — give it a truly mechanical feel.

A new solar charging system
that frees up dial design

By adopting a low-power Bluetooth® system, we reduced the solar-receptive area of the ECB-S100 to about 45% that of the previous ECB-900 model.
This allows for a higher degree of freedom in face design while still ensuring stable power for the watch’s rich functionality.

A countdown indicator for punctuality

An inset dial indicator at the 9 o’clock position counts down to the next alarm and shows the time remaining in the active timer.
This countdown begins with a progress beep 30 minutes in advance and ends with an alarm tone when time is up.
Set alarms and timers with ease using the smartphone app.
Developed with feedback from racing teams who need to manage their minute-to-minute race week schedules.
