Setup
1. Initial Winding (Automatic Movement)
Your Timex Deep Water watch is powered by an automatic mechanical movement. It winds itself with the motion of your wrist. If the watch has stopped or is running low on power, it can be manually wound:
- Ensure the crown is in position 1 (fully pushed in).
- Rotate the crown clockwise approximately 20-30 times. This will provide enough power reserve to start the watch.
- Once worn, the natural motion of your arm will keep the watch wound.
2. Setting Time and Date
- Unscrew the Crown: The crown is a screw-down type for water resistance. Rotate the crown counter-clockwise until it springs out to position 1.
- Set Date: Gently pull the crown out to position 2 (first click). Rotate the crown clockwise or counter-clockwise to adjust the date. Avoid setting the date between 9 PM and 3 AM, as this can damage the movement.
- Set Time: Pull the crown out further to position 3 (second click). The second hand will stop. Rotate the crown to set the hour and minute hands. To ensure accurate time setting, align the minute hand a few minutes past the desired time, then rotate it back.
- Synchronize: Once the time is set, push the crown back to position 1 when a time signal (e.g., from a radio or phone) reaches the 12 o'clock mark.
- Screw Down the Crown: Push the crown firmly back into the case and rotate it clockwise while pushing, until it is securely screwed down. This is crucial for maintaining water resistance.

3. Adjusting the Strap
The watch features a synthetic rubber strap with quick-release spring bars and a special slip-thru sport closure. To adjust the fit, simply slide the strap through the buckle and secure it at the desired length. The quick-release spring bars allow for easy strap removal and replacement if desired.

Operating the Watch
Timekeeping
Once set, your automatic watch will keep time as long as it is worn regularly or kept on a watch winder. The movement has a power reserve that allows it to run for a period (typically 38-40 hours) when not worn.
Using the Rotating Bezel
The unidirectional rotating top ring (bezel) can be used to measure elapsed time, typically for diving or other timed activities. To use:
- Rotate the bezel counter-clockwise to align the zero marker (triangle) with the minute hand at the start of your activity.
- Read the elapsed time on the bezel against the minute hand.
Water Resistance
This watch is water resistant up to 200 meters (660 feet). This makes it suitable for professional marine activity and serious surface water sports, but not for saturation diving. Always ensure the crown is fully screwed down before exposing the watch to water.
- 200M (20 ATM): Suitable for swimming, snorkeling, and recreational diving.
- Do not operate the crown or pushers (if any) while the watch is submerged in water.
- Avoid exposing the watch to sudden temperature changes, as this can compromise water seals.
Maintenance
Cleaning
To maintain the appearance of your watch:
- Wipe the case and sapphire crystal with a soft, lint-free cloth.
- For the rubber strap, use mild soap and water, then rinse thoroughly and dry.
- After exposure to saltwater, rinse the watch with fresh water and dry it completely.
Storage
When not wearing your watch for extended periods, store it in a cool, dry place away from direct sunlight and strong magnetic fields. If you wish for the watch to keep running, consider using a watch winder.
Servicing
Like all mechanical watches, your Timex Deep Water watch requires periodic servicing to ensure optimal performance and longevity. It is recommended to have the watch serviced by an authorized Timex service center every 3-5 years.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch has stopped or is running slow. | Insufficient power reserve. | Manually wind the watch by rotating the crown 20-30 times clockwise. Wear the watch regularly to keep it wound. |
| Date changes at noon instead of midnight. | Time is set for AM/PM incorrectly. | Advance the hour hand by 12 hours. |
| Moisture or condensation under the crystal. | Crown not fully screwed down, or seals compromised. | Immediately take the watch to an authorized service center. Do not attempt to dry it yourself. |
| Watch not keeping accurate time. | Exposure to strong magnetic fields, or needs servicing. | Keep watch away from magnets. If problem persists, contact an authorized service center for demagnetization or servicing. |
