• Position 2 (Fully Out): Time setting mode (hacking enabled)

Pushers:

• Top Right (Button A): Start/Stop chronograph

• Bottom Right (Button B): Reset chronograph to zero

Tip: To reset the chronograph hands to zero (if misaligned), enter hand re-calibration mode by pulling the crown to position 2 and using the pushers to realign.

Battery Replacement and Servicing

• Battery Replacement: Use only SR927W high-drain silver oxide cell.

• AC Reset: Perform an AC reset after battery installation by bridging the reset contact with battery edge using tweezers.

• Gasket Replacement: Always replace gaskets during battery change, and pressure-test water-resistant cases.

• Hand Installation: Use calibrated tools and check hand alignment to ensure proper chronograph reset.

Common Issues

• Chronograph Seconds Hand Does Not Reset Properly: Calibrate the hands using the crown in position 2 and the pushers.

• Chronograph Stops Prematurely: Check for debris or mechanical resistance in reset springs or pusher mechanisms.

• Watch Stops Unexpectedly: Battery may be low or there may be a short circuit—clean contact surfaces and replace battery if needed.

• Date Doesn’t Change: Avoid adjusting the date between 9:00 PM and 3:00 AM. If issue persists, inspect calendar gear for wear or misalignment.

• Pushers Stick: Dirt or dried lubricant—clean and relubricate during servicing.
