OFFICIAL Corum Service Center
Corum services are all carried out to Corum's high standards, and come with a 1 year warranty.
Although Corum movements are assembled with the utmost care, their accuracy can be affected by the influence of gravity, magnetic fields, shocks and most probably by ageing oils. Also the water resistance may be impaired by the ageing of gaskets or by an accidental shock.
Indeed, the precision of a mechanical movement depends on several factors, but essentially on the balance-spring/balance/escapement drive train, known as the regulating organs.
A complete overhaul of the watch is recommended every 3 to 5 years depending on the conditions in which it is used. Water resistance should be annually checked by a Corum official dealer or an authorized service centre.
