Special recommendations

entirely on the model, the climate and the owner's indi- vidual care of the watch. As a general rule, a watch should be serviced every 4 to 5 years, depending on the condi- tions in which it is used.

Who should I contact for a maintenance service or battery replacement?

We recommend that you contact an approved OMEGA ser- vice centre or authorised OMEGA retailer, who are the only entities equipped with the tools and apparatus required to carry out the work and the necessary checks in a pro- fessional manner. Furthermore, only these entities can guarantee that their work is carried out in accordance with OMEGA's strict quality standards.

Environmental protection

Used batteries, watch components and electronic watches should not be thrown away. They should be recycled correctly. We recommend you return them to your nearest OMEGA retailer.

Leather straps

OMEGA recommends that you follow the steps below in order to preserve the condition of your leather strap for as long as possible:

•Avoid contact with water and dampness to prevent discoloration and deformation.

•Avoid prolonged exposure to sunlight to prevent the colour from fading.

•Do not forget that leather is permeable! Therefore avoid contact with greasy substances and cosmetic products.

•If you have a problem with your leather strap, please contact your nearest OMEGA retailer.
