1.4   What are the service intervals?
Every 24 months
we advise you to do maintenance service 
(water resistance, movement accuracy 
test).
Every 5 years
we advise you to do a complete mainte-
nance service (complete movement revi-
sion, water resistance, accuracy and 
functionality complete revision).
Who should I contact for a 
maintenance service or battery 
replacement?
We recommend that you contact an au-
thorized Edox retailer, as they are the only 
certified specialists equipped with the 
tools and apparatus required carrying out 
the work and the necessary checks in a 
professional manner. Furthermore, only 
these certified specialists can guarantee 
that their work is carried out in accord-
ance with Edox’ strict quality standards. 
Make sure that right after each battery 
change the watch has been water-re-
sistant tested.
1.5  Environmental protection
Collection and treatment of end of life 
Quartzwatches*
This product should not be disposed of 
with household waste. It has to be re-
turned to a local authorized collection 
system. By following this procedure you 
will contribute to the protection of the en-
vironment and human health. The recy-
cling of the materials will help to conserve 
natural resources.

countries with corresponding legislation.
2.  PRECISION TOLERANCES
Mechanical watches
The mechanical Edox watch with an auto-
matic movement does not need to be 
wound by hand. 
The motion of your wrist makes the rotor 
(oscillating weight or mass) turn, thereby 
winding up the mainspring of the watch 
movement. 
The everyday activity of life is sufficient in 
itself to wind up an automatic Edox watch 
and it will run continually, even if it is re-
moved at night. However, if not worn for 
approximately 40 hours, it will stop. To 
make the watch work again, turn the 
crownclockwiseabout20times.Nowset
the time and if possible the date, etc.
2.1 Mechanical watches accuracy
Depending on the movement, the daily 
tolerance of a mechanical watch can be of 
30 seconds. If you notice a bigger toler-
ance rate, you can have your watch ad-
justed at a service center in your country, 
free of charge within the guarantee peri-
od.
2.2   Chronometer watches accuracy
Every Edox Chronometer comes with a 
rating certificate issued after an official 
test by the Swiss Official Chronometer 
Testing Institute (COSC). The accuracy of 
the watch movement is tested electroni-
cally at the COSC during 15 days in differ-
ent positions and at different 
temperatures. The average daily rating 
must not exceed -4/+6 seconds per day.
Only Edox watches which have success-
fully undergone the official COSC rating 
procedure qualify as chronometers.
3.  GENERAL INFORMATIONS
3.1  Helium escape valve
Decompression system which allows he-
lium to escape from inside the watch 
when the watch is worn for professional 
use in pressure chambers. (Long-term 
underwater work, crude oil exploration, 
etc.)
Important: The Edox helium valve opens 
and closes automatically (for the models 
wearing the new automatic Helium es-
cape valve). The models wearing a non-
automatic Helium escape valve must have 
the valve screw down in order to guaran-
tee the water resistance of the watch. 
Unscrew the Helium escape valve only to 
release the gas from the watch. Do not 
unscrew it under water in order to prevent 
water entering the mechanism.
3.2  Tachymeter scale 
Some Edox Chronograph watches have a 
tachymeter scale. With this scale it is pos-
sible to measure the speed. The distance 
is 1 km. To measure the elapsed time 
press the start/stop button when the vehi-
cle (power-boat) passes the starting and 
the final point or target. The figure shown 
by the hand on the tachymeter scale indi-
cates the average speed in kilometers. If 
for instance a car covers a 1 km distance 
in 30 seconds, you can consider it to an 
average speed of 120 km per hour.
