The natural brown wood grain frame brings a soft impression to offices and public spaces that tend to be impersonal.

The watch is equipped with a sleep second hand function , which detects brightness and stops the second hand at the 12 o'clock position when it gets dark. When it gets bright again, the second hand starts moving again to match the 00 second mark.
