SPECIAL CHARACTERISTICS
RIDER-TAB BEZEL
The bezel of your watch is fitted with 4 hour-mark-
ers called rider-tabs: they are used as points of refer-
ence to mark the time of departure or a limit time
one wishes to remember. On models with no chrono-
graph functions, they also serve as "minute chrono -
graph" enabling one to measure time elapsed in
minutes.
Rider-tabs make it easier to rotate the bezel by giv-
ing a better grip (especially when wearing gloves)
and additionally protect the glass.
