4. Operation
4.1 Water Resistance
Your Timex Marlin Jet watch is water resistant up to 50 meters (164 feet). This means it is suitable for short periods of recreational swimming, but not for diving or snorkeling. Avoid operating the crown while the watch is wet or submerged to prevent water intrusion.
- 30m (100ft): Splash resistant.
- 50m (164ft): Suitable for short periods of recreational swimming.
- 100m (330ft): Suitable for swimming and snorkeling.
- 200m (660ft): Suitable for diving.
Note: Water resistance ratings are based on laboratory pressure tests. Actual water resistance may vary over time due to wear and tear, temperature changes, and impacts.

5. Maintenance and Care
- Cleaning: Wipe the watch case and bracelet with a soft, damp cloth. For stainless steel, a mild soap solution can be used, followed by thorough rinsing and drying. Avoid harsh chemicals.
- Battery Replacement: This watch uses a Lithium Metal battery. When the battery needs replacement, it is recommended to take it to an authorized Timex service center or a professional watch repair shop to ensure proper sealing and maintain water resistance.
- Avoid Extreme Temperatures: Do not expose your watch to extreme temperatures (above 60°C / 140°F or below 0°C / 32°F) or sudden temperature changes.
- Magnetic Fields: Keep the watch away from strong magnetic fields, as they can affect the accuracy of the quartz movement.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch stops or runs intermittently | Depleted battery | Replace battery (professional service recommended). |
| Time is inaccurate | Strong magnetic field exposure, crown not fully pushed in | Reset time, ensure crown is fully pushed in. Keep away from magnets. |
