Every Brillier timepiece is designed and manufactured to exceed the highest of standards. Unlike most other mechanical objects, a watch operates non-stop. In order to ensure optimal performance and longevity from your timepiece, please review the simple guidelines for care and precautions of your new Brillier timepiece.

Your timepiece is a complex integration of parts and components brought together by skilled craftsmen. There are certain actions or environmental situations that may damage or impede your timepiece’s ability to perform optimally. 

To ensure your Brillier watch provide you with precise time keeping and optimal service for many years, please take note of these special recommendations:

  • Service is required on your Brillier watch every twelve months to inspect and ensure the condition of your gaskets for water resistance and lubricate the moving parts in the movement.
  • Magnetic fields: avoid placing your watch on loudspeakers or refrigerators, since they generate powerful magnetic fields.
  • Swimming in the sea: always rinse your watch with warm water afterwards.
  • Shocks: whether thermal or other, avoid them.
  • Screw-in crown: screw in the crown carefully to prevent water from penetrating the mechanism.
  • Non screw-in crown: push it back into the neutral position to prevent water from entering the mechanism.
  • Cleaning: for metal bracelets and water-resistant cases, use a toothbrush with soapy water to clean and a soft cloth for drying.
  • Chemical products: avoid direct contact with solvents, detergents, perfumes, cosmetics, etc., since they may damage the bracelet, case, or gaskets.
  • Temperature: avoid exposure to extreme temperatures (greater than 60° C, or 140° F, less than 0° C, or 32° F) or extreme temperature changes.
  • Water resistance: a watch’s water resistance cannot be permanently guaranteed. It may be affected by ageing of gaskets or by an accidental shock to the crown. As stipulated in our service instructions, we recommend you have the water resistance of your watch checked once a year by an approved BRILLIER service agent.


Like any precision instrument, a watch needs regular servicing to ensure that it functions perfectly. As a general rule, a watch should be serviced every year. Mechanical and Quartz movements that are the machines in your watch, have several moving parts which need to be lubricated and checked periodically to ensure perfect time keeping and long life.
