Setup
Initial Winding
Your automatic watch is powered by the motion of your wrist. If the watch has stopped or is running low on power, it may require an initial manual winding. To do this, gently rotate the crown clockwise approximately 20-30 times until the second hand begins to move consistently. This will build up a power reserve.
Setting the Time
- Pull the crown out to the furthest position.
- Rotate the crown clockwise or counter-clockwise to set the hour and minute hands to the correct time.
- Once the time is set, push the crown back into its original position to start the watch.
Bracelet Adjustment
The silver-tone adjustable link bracelet can be resized for a comfortable fit. It is recommended to have this adjustment performed by a qualified jeweler or watch technician to prevent damage to the links or clasp.

Operating Your Watch
Automatic Movement
This watch features an automatic mechanical movement. It does not require a battery. The movement is powered by the natural motion of your arm. When worn regularly, the watch will remain wound. If the watch is not worn for an extended period, it may stop and require manual winding as described in the "Initial Winding" section.
Water Resistance
Your Armitron watch is water resistant to 165 feet (50 meters). This rating indicates that the watch is suitable for short periods of recreational swimming, but it is not designed for diving or snorkeling. Avoid operating the crown or pushers while the watch is wet or submerged to prevent water intrusion.

This chart illustrates various water resistance ratings. Your watch is rated for 50M (165FT), suitable for recreational swimming.

Maintenance
- Cleaning: Wipe the watch case and bracelet regularly with a soft, dry cloth to remove dirt and oils. For the bracelet, a slightly damp cloth can be used, followed by immediate drying.
- Avoid Extreme Conditions: Protect your watch from extreme temperatures, direct sunlight for prolonged periods, and strong magnetic fields, as these can affect the accuracy of the automatic movement.
- Servicing: While automatic watches are designed for longevity, periodic servicing by a professional watchmaker is recommended every 3-5 years to ensure optimal performance and water resistance integrity.
Troubleshooting
- Watch Not Running or Losing Time:
As an automatic watch, it requires motion to operate. Ensure you are wearing the watch regularly. If it has stopped, manually wind it as described in the "Initial Winding" section. If the issue persists, the movement may require professional inspection.
- Condensation Under Crystal:
Small amounts of condensation may appear temporarily due to sudden temperature changes. If condensation is persistent or appears as large droplets, it indicates a breach in the water resistance. Seek immediate professional service to prevent damage to the movement.
