Setting the Time and Date
- Pull out the crown: Carefully pull out the crown. The second hand stops (hacking function) to protect the movement.
- Turn the hands forward: Turn the hands clockwise until the minute hand passes the desired minute slightly.
- Turn the hands backward: Turn the hands back to approximately 5:55, then forward again until the date changes (if applicable).
- Repeat: Repeat this step until the correct day of the week or date is reached. Then set the exact time and push the crown back in firmly.
Installing the Battery
Loosen the retaining ring using the appropriate case key and remove the case back (for non-waterproof models, insert the case opener into the recess).
- Slightly loosen the coil carrier screw. Caution! This screw must not be loosened by more than a quarter turn, as otherwise the battery clip may become jammed on the insulating pin on the coil carrier, preventing contact with the circuit after step 5.
- Loosen the battery bracket screw and swing out the battery bracket (see illustration).
- Insert the battery with the W-4 mark facing down and the yellow protective layer facing up. (historically W-4 or the modern replacement model 344 / SR42)
- Put the battery bracket back in place and tighten both screws.
- Replace the case back. For water-resistant models, the gasket must be positioned precisely. Note: If the second hand does not move, check whether the hand shaft is in the normal position. If so, tap the case lightly—at the “3” o’clock or “9” o’clock position—to set the tuning fork in motion.
