Other maintanance advice
Use a small brush (for ex. a toothbrush) with soapy water for metal bracelets and water-resistant cases. Afterwards, use a soft cloth to dry it that you do not scratch the watch.
Changing the battery
Depending on watch type and wearing habits, the batteries can last from two to five years. An empty battery must be changed as soon as possible to avoid the risk of leakage resulting in damage to the movement. We recommend that you take your watch to an authorized Aviator Service Center to have the battery changed
To keep your watch in perfect working conditions and make it last longer you should have your Aviator watch to undergo regular maintenance service. Generally, it is recommended to have a complete maintenance service.
