Can a mechanical watch be worn playing sports?
In general yes. All or nearly all mechanical watches manufactured today are equipped with anti-shock devices that protect the watch’s balance-staff pivots the part of the watch movement most vulnerable to damage from impact. These devices are usually effective enough to protect the watch from the shock it encounters when you hit a tennis or golf ball, for instance. Nonetheless, there is a small change that an especially hard knock could damage not only the balance but the rotor axle, which in some automatic movements serves to secure the rotor to the watch movement. So deciding whether to wear your mechanical watch or not while playing sports is a matter of risk assessment. The odds, however, are on your side.
