A mechanical watch movement works under the most difficult conditions. Fluctuating temperatures, shocks, magnetism and dust have a negative effect on the movement. Therefore, your watch should be serviced regularly, even when it seems to be in good condition. We suggest you to having your watch waited every five to six years. Our watchmakers are happy to take this responsible task of revision. In a revision we decompose the movement into its component parts, clean them in a special bath, check and replace worn parts if necessary. After thoroughly cleaning the movement is reassembled and re-oiled. Finally, we replace all the seals and the watch is subjected to a pressure test. Once your watch has passed our final inspection, you will get back the watch with a two-year functional guarantee.
