This tough structure is designed to withstand three types of gravitational acceleration: external shocks, centrifugal gravity and vibrations.

Fine resin parts (FRP) are installed at both ends of the band shaft and fixed with carbon FRP stoppers, strengthening the connections between case and band.

3-way Time Sync
Accurate timekeeping is assured by the installation of three advanced time-correction systems: terrestrial radio wave reception (Multi Band 6),
GPS satellite signal reception and Bluetooth® transmission.
The most appropriate system is selected automatically depending on the conditions,
and the correct time is displayed for the current time zone anywhere in the world.
