It is NOT suitable for diving, snorkeling, or prolonged water exposure. Always ensure the crown is fully pushed in before any contact with water.

- Comprobe se a coroa está completamente inserida. Se a tira cara a fóra, o reloxo non funcionará.
- The Meca-Quartz movement requires a battery. If the watch stops completely, the battery may need replacement. Contact a qualified watch technician for battery replacement.
6.2 As manecillas do cronógrafo non se poñen a cero
If the chronograph hands do not return precisely to the 12 o'clock (zero) position after resetting, they may need calibration. This can sometimes occur after a battery change or impact.
- Pull the crown out to the outermost position (time setting position).
- Press the top pusher repeatedly to advance the chronograph second hand until it aligns with the 12 o'clock position.
- If other chronograph sub-dials are misaligned, use the bottom pusher to adjust them to their zero positions.
- Once all chronograph hands are aligned, push the crown back into its normal operating position.
