A / GENERAL INFORMATION
WATCH PRECISION
A mechanical movement, whether manual or automatic
(self-winding), is a complex assembly of gears, gear
trains and other components often not much bigger than
a single strand of hair. A watch's precision is determined
by the spiral balance wheel, the heart of the watch, which
regulates the rate of time through its oscillations. Oscilla-
tion frequency varies depending on the model and can be
anywhere between 3 and 4 Hz, it is therefore important to
bear in mind that, despite the great care taken in assem-
bling your watch and its movement, it is nevertheless not
as precise as a quartz watch, with an oscillation of 32,000
Hz. Further, rate variations may still occur, caused by a
variety of factors, including impact, the aging of the oils,
significant temperature fluctuations, magnetic fields, and
wearer activity.
In general and depending on the model, your watch time
may vary by 1 to 2 minutes per week.
B / USER GUIDE
This guide explains all the functions available for different
Baume & Mercier watch models.
To adjust your watch, please refer to the inside cover of
this guide and the diagram which most closely resembles
your watch dial. Then follow the directions corresponding
to your model.
Note on screw-down crowns : Your Baume & Mercier
watch may come with a screw-down crown. If so, you must
first unlock the screw-down crown by turning it counter-
clockwise before adjusting the date or the time or winding
the watch.
Once you have finished adjusting your watch, press lightly
on the crown while turning gently clockwise, tightening it
down again until you feel some resistance. If the crown is
not correctly screwed-down, your watch may no longer be
completely water-resistant.
