FEATURES

24 hours GMT

  • A GMT function means that the watch has a second hour hand which completes one full rotation in 24 hours and a 24‑hour index on the dial. Particularly useful for wearers who wish to track two time zones.

Chronograph

  • Complicated watch with a function for measuring short time periods in addition to its function for permanently displaying hours, minutes and seconds.

Chronometer

  • Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).

Date

  • The day of the month, displayed in a window on a watch dial typically at the 3 o'clock or 6 o'clock position.

Helium escape valve

  • Decompression system which allows helium to escape from inside the watch when the watch is worn for professional use in pressure chambers. (Long‑term underwater work, crude oil exploration, etc.)

Screw-in crown

  • Self‑locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.

Small seconds

  • A hand on a sub‑dial which tracks seconds typically it completes a full rotation in one minute.

Unidirectional rotating bezel

  • A bezel which turns in only one direction. Particularly useful for divers who cannot accidentally rotate it in the wrong direction, which could cause them to miscalculate their dive times. A rotating bezel makes it easy to measure elapsed time.
