Precautions Concerning Water-Resistance
A watch's water-resistance can be affected by gasket drying or accidental crown shocks. To maintain water-resistance:
- Rinse in soft water after contact with sea water.
- Have water-resistance checked annually by an approved LONGINES Service Centre.
- Never open the watch yourself.
IMPORTANT! Never activate the time-setting crown and/or push-pieces when the watch is underwater. Ensure the crown and push-pieces are pushed in or screwed down before any immersion in water.
⚠️ WARNING: KEEP THE BATTERY OUT OF REACH OF CHILDREN. The battery can cause serious injuries if swallowed or placed inside any part of the body. Seek medical attention immediately.

Setting the Time – General Information
Your watch displays hour, minute, seconds, and date.
Screw-in Crown
Some LONGINES models feature a screw-in crown. It must be unscrewed before setting the time, correcting the date, or winding. After these operations, return the crown to position 1, push it back in, and screw it firmly to ensure water-resistance.
Setting the Time
To set the time:
- Pull the crown out to position 3 when the seconds hand is at 60.
- Turn the crown forwards or backwards until the desired time is displayed.
- Push the crown back in to position 1.
Quick Date Correction
Do not attempt quick correction of the date between 8 p.m. and 3 a.m.
To correct the date:
- Pull the crown out to position 2 and turn it forwards. Your watch continues to operate, so the time does not need resetting.
- Push the crown back in to position 1.
The date needs correcting after any month with fewer than 31 days. The date changes when the hour hand passes midnight.
