RIDER-TAB BEZEL
the bezel of your watch is fitted with 4 hour-markers
called rider-tabs: they are used as points of reference to
mark the time of departure or a limit time one wishes
to remember. On models with no chronograph func-
tions, they also serve as "minute chronograph"
enabling one to measure time elapsed in minutes.
rider-tabs make it easier to rotate the bezel by giving a
better grip (especially when wearing gloves) and
additionally protect the glass.

SUN COMPASS
Your B
chronometer may be used as a sun compass, thus enabling
reItLIng
you to determine the northerly-Southerly direction. For regions that have
instated daylight saving time, subtract one hour when directing the watch.
In the Northern hemisphere
Point the hour hand precisely towards the sun. In relation
to the watch dial, the point located midway between
the current time and 12 o'clock indicates the South, the
north being exactly opposite.
In the Southern hemisphere
Point the hour-marker located at 12 o'clock on the dial
precisely towards the sun. In relation to the watch dial,
the point located midway between the current time and
12 o'clock indicates the north, the South being exactly
opposite.
