Precautions concerning water resistance
A watch’s water-resistance can be affected by changes caused by the gaskets drying out, or an accidental shock to the crown. To help maintain your watch’s water-resistance, we recommend rinsing it in soft water after any contact with sea water and having its water-resistance checked once a year by an approved LONGINES Service Centre. In no circumstances should you open your watch yourself.
IMPORTANT! Never activate the time-setting crown and/or push-pieces when the watch is underwater and ensure that 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.

A Crown
B Hour hand
C Minute hand
D Seconds hand
E Date window
F 24-hour indicator
2 Push-piece for opening the case-back
24-hour, minute, seconds and date display.
Screw-in crown
Some LONGINES models are equipped with a screw-in crown, which must be unscrewed before setting the time, correcting the date or winding, by turning it anti-clockwise. After making the settings, return the crown to position 1, then push it back in and screw it in firmly to ensure the watch’s water resistance.
Setting the time and stop seconds
Pull the crown out to position 3 when the seconds hand is at 60. Turn the crown either way to the desired time display. As soon as the time is synchronized, push the crown back into position 1. If you have not been wearing your mechanical watch, it needs to be wound manually through thirty revolution ns or so.
Avoid any quick date correction between 20:00 and 03:00.
Quick date correction
Pull the crown out to position 2, and then turn it forward to the desired date display. During this operation, your watch will continue to run; no time adjustment will be required. The date needs to be corrected after every month shorter than 31 days.
Push the crown back into position 1. The date will change when the hour hand passes midnight.
Push-piece 2
