SPECIAL CHARACTERISTICS
DECOMPRESSION VALVE
To avoid a potential explosion when returning to the surface, the case of your Breitling
chronometer is fi tted with a decompression valve that vents the gases – mostly helium –
that accumulate in the case during prolonged immersion at great depths.

SPECIAL CHARACTERISTICS
UNIDIRECTIONAL BEZEL WITH INDEX MARKERS
The bezel of your watch is marked with 12 index markers: they
are used as points of reference to mark a start time or a limit
time you wish to remember. On models with no chronograph
functions, they also provide a "minute chrono" function enabling
you to measure the elapsed time in minutes.
For safety, the bezel can only turn counterclockwise.
