Maintaining the accuracy of my watch?
Heat and cold have an effect on the accuracy of a quartz watch. Watches which
are fitted with quartz oscillating crystals are designed to function optimally
under room temperature. A temperature of 100 Fahrenheit will throw the timing
off by 1 second a day, as well as one of 32 Fahrenheit.
However, for a mechanical watch to differ by 1 second a day or less is not a
very big factor since we do not expect the same accuracy as a quartz watch.
Advances in metallurgy have also very well controlled the effects of temperature
on watch accuracy. This is why some self-winding watches are subjected to
extremes in temperature to be certified as chronometer standard.
A watch should also not be exposed to extreme temperature. This affects the
viscosity of the oil that lubricates the movement, and thereby affects the
Wearing my watch?
A watch should always be worn on the outside of the wrist (not inside), with
the dial up and the crown down (nearer the hand than the elbow). Most watches
are regulated based on the right handed person, so this means the watch is worn
on the left wrist, with the components in proper position. Any other position
may yield some differences in accuracy unless otherwise regulated at the desired
position. This is true only for mechanical watches.
It is also not proper to wear a watch too loosely
as it may loosen the individual links of the bracelet and clasp when constantly
exposed to shock. A watch worn too tight on the other hand may deform the
bracelet, apart from giving an uncomfortable fit.
Nearly all mechanical watches are equipped with anti-shock devices that protect
the watch's balance-staff pivots-parts of the watch movement most vulnerable to
damage from impact such as those encountered from tennis or golf. Nonetheless,
there is a small chance that a hard knock could damage not only the balance but
also the rotor axle. So deciding whether or not to wear your mechanical watch
when playing sports is a matter of risk assessment.
