Jaermann & Stübi watches are produced to very high standards of quality. It is worth remembering that the mechanical parts run 24 hours a day when used, so the watch must undergo regular maintenance to ensure long life and good operation.
Have your watch checked periodically for water-resistance by an Authorized Jaermann & Stübi Service Centre and restore it every two years with regular servicing, or whenever the watch has to be opened. Restoring the watch’s water-resistance necessarily involves replacing the seals so as to ensure the maximum water-resistance and security. Where the watch is used in underwater sports activities, it is recommended that it should be checked every year before the season of underwater activities begins.
Have the movement of your watch checked periodically by an Authorized Jaermann & Stübi Service Centre so as to maintain its perfect operation. If the watch tends to gain or lose time significantly, the movement may need to be overhauled. The movements are designed to withstand temperature variations between -10°C and +60°C (14°F and 140°F). Outside this range of temperatures, operational variations exceeding those set out in the specifications of the movement may be noticed. In addition, there is a risk that the lubricants contained in the movement may deteriorate, resulting in damage to some of its parts.
CLEANING THE EXTERIOR
To keep the exterior in perfect condition, we recommend washing your Jaermann & Stübi watch with soap and warm water, using a soft brush. After this operation, and also after bathing in the sea or a swimming pool, carefully rinse the watch with clean water. All Jaermann & Stübi watches can be cleaned with a soft, dry cloth.
Jaermann & Stübi straps must be washed in warm water and left to dry. It is important not to dry them on a hot surface or to expose them to direct sunlight, because the rapid evaporation of the water could damage their shape and quality. After each bathe in the sea or a swimming pool, carefully rinse the strap with clean water. The leather strap is made from leather which has not been chemically treated, which gives it a very natural, soft feel. As a result of its characteristics, the colour and form of the leather tend to change with the passage of time while maintaining all of its beauty. It is recommended that the strap and the buckle should be replaced by an Authorized Distributor or a Jaermann & Stübi Service Centre, in order to avoid any problems caused by incorrect replacement. Only an Authorized Distributor or Jaermann & Stübi Service Centre can guarantee the use of genuine Jaermann & Stübi straps, properly designed to fit the dimensions of the case and manufactured according to the quality standards of the brand.
