II. MECHANICAL WATCHES
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. Oscillation 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
assembling 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 identify its icon
diagram located on the inside cover of this guide, 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.
