WATER-RESISTANCE
The water-resistance cannot be guaranteed
permanently. Everyday wear, ageing of
seals or accidental shocks adversely affect
the water-resistance of the watch. We rec-
ommend that you have the water-resistance

6. KEY WORDS
Screw-in crown:
Some watches — usually those water-resistant
to more than 5 ATM — can have a screw-in
crown. Before being able to make any adjust-
ments (change the date, set the time, etc.) the
crown has to be unscrewed. To do so, please
proceed as follows:
–
Power reserve indicator:
Some automatic watches have a power reserve
–
indicator. If the watch is worn rarely or not at all
the power reserve indicator will gradually de-
–
crease. When the watch is wound or worn the
power reserve indicator will gradually increase.
✓
End Of Life (EOL) function:
✓
EOL function only features on some quartz
movements and indicates the end of battery life.
If the second hand starts to jump every 4 sec-
onds, we recommend that you replace the bat-
tery immediately.
Tachymeter or tachymiler scale:
Some dials feature a tachymeter scale: it meas-
ures speed (in km per hour) for a covered dis-
tance of 1 km or 1 mile.
Example: 1000 meters covered in 45 seconds
corresponds to a speed of 80 km per hour.
Carat:
The weight of a diamond is measured in carats,
one carat being equal to 0.20 gram.
