Water Resistance
The Timex Ironman Triathlon Transit+ Watch is water-resistant to 100 meters (330 feet). This makes it suitable for snorkeling, as well as swimming, but it is not recommended for diving.
Important: To maintain water resistance, do not press any buttons under water unless your watch is indicated as 200 meter water resistant. Watches labeled water-resistant without a depth indicated can withstand splashes and rain, but should not be submerged.

Maintenance
Cleaning Your Watch
Regularly clean your watch with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials that could damage the watch case or strap.
Battery Replacement
The watch uses a CR2032 battery. When the battery needs replacement, it is recommended to have it done by a qualified watch technician to ensure proper sealing and maintain water resistance. The battery compartment is located on the back of the watch.

Troubleshooting
Watch Not Responding / Resetting

Inaccurate Heart Rate Readings

Inaccurate Activity Tracking
