FEATURES

Anti-magnetic

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

Chronometer

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

Master Chronometer Certified

Guaranteeing the Swiss industry’s highest standard of precision, performance and magnetic-resistance, as set by the Swiss Federal Institute of Metrology (METAS).

Screw-in crown

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

Time zone function

Allows the hour hand to be easily adjusted to different time zones without stopping the watch.

Transparent caseback

A transparent caseback - 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.
