Maintenance and Care
Water Resistance
Your Timex Expedition Shock watch is water resistant to 100 meters (330 feet). This means it is suitable for recreational swimming, showering, and snorkeling. Do not press any buttons while the watch is submerged, as this can compromise the water resistance seal. Avoid exposure to hot water or steam, which can damage the seals.
Shock Resistance
The watch is designed to be shock resistant to I.S.O. standards. While durable, avoid unnecessary impacts to prolong its life.
Cleaning
Clean your watch regularly with a soft, damp cloth. For the resin band, mild soap and water can be used. Ensure the watch is completely dry before storing or wearing.
Battery Replacement
The watch uses 1 Lithium Metal battery (included). When the display dims or functions become erratic, it may be time for a battery replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure the water resistance seal is properly maintained.
