Setup and Adjustments
Setting the Time
- Pull the crown (A) out to the outermost position.
- Turn the crown clockwise or counter-clockwise to set the hour and minute hands to the correct time. Ensure AM/PM is correctly set, especially when setting the date.
- Push the crown (A) back into its normal position to start the watch.
Setting the Date
- Pull the crown (A) out to the middle position.
- Turn the crown clockwise to advance the date hand to the correct date.
- Push the crown (A) back into its normal position.
Setting the Day of the Week
- Press the pusher (C) repeatedly until the day of the week sub-dial displays the correct day.
Setting the Month
- Press the pusher (B) repeatedly until the month sub-dial displays the correct month.
Setting the Moon Phase
The moon phase sub-dial advances automatically with the time. To set it initially or correct it:
- Pull the crown (A) out to the outermost position (time setting position).
- Advance the time until the moon phase display shows the correct phase for the current date. This may require advancing the time through several days. Refer to a reliable moon phase calendar for accuracy.
- Once the moon phase is set, adjust the time to the current time as described above.
Operating Your Watch
Your Timex Marlin Moon Phase watch is a quartz movement timepiece, powered by a battery. It provides accurate timekeeping and displays various calendar functions.
Water Resistance
This watch is water resistant to 50 meters (5 ATM). This means it is suitable for short periods of recreational swimming, but not for diving or snorkeling. Avoid operating the crown or pushers while the watch is wet or submerged to prevent water intrusion.
Maintenance
Cleaning
Wipe the watch case and crystal with a soft, dry cloth. For the leather strap, avoid prolonged exposure to water and harsh chemicals. Clean with a damp cloth and mild soap if necessary, then dry thoroughly.
Battery Replacement
The watch is powered by one Lithium Metal battery. When the watch stops running, the battery needs to be replaced. It is recommended to have battery replacement performed by a qualified watch technician to ensure proper sealing and water resistance.

Troubleshooting
- Watch not running: Check if the crown is pushed in completely. If it is, the battery may need replacement.
- Time/Date incorrect: Refer to the "Setup and Adjustments" section to reset the time, date, day, and month.
- Moon phase incorrect: The moon phase sub-dial is linked to the time. If the time is advanced past midnight, the moon phase will advance. Ensure the time is set correctly, and then adjust the moon phase as described in the setup section.
- Water inside the watch: If moisture appears inside the watch, have it inspected by a professional watch repair service immediately to prevent damage.
