Your watch is a fine instrument. Please treat it with care and avoid violent shocks and knocks as it will leave marks on the case (especially on gold cases) or it can harm the inner mechanism of your watch. Please also do not leave your watch in an area with too high temperatures (i.e. car in direct sun) or strong magnetic fields (loudspeaker boxes) to avoid damages to the mechanism. The balance wheel in an automatic Alpina watch swings 28,800 times an hour and the gear train moves forward 691,200 times in 24 hours. In four years, this represents over one billion impulses. We advise you to bring your watch every 3-4 years to an official Alpina Retailer where a trained watchmaker will meticulously inspect it before cleaning and lubricating the movement thoroughly. You may check the Retailer Locator at www.alpina-watches.com/en/retailer.php for a service center near you or contact the Distributor in your country.
