  • The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).


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


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


  • 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.)


  • Liquidmetal is an alloy which is considerably harder than stainless steel yet bonds seamlessly with ceramics. The blended materials are particularly resistant to scratching and corrosion.

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.

Transparent case back

  • A transparent case back ‑ frequently made of sapphire ‑ makes it possible to see the movement inside the watch.

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.
