The service interval of a watch depends on its use and the environment in which it is worn. Water resistance may be affected by worn seals or accidental impacts. We therefore recommend that you check the water resistance once a year and have a full service performed every five to eight years. We always recommend that you visit an authorized service center.
After long periods of rest, before putting your automatic Favre-Leuba watch back on your wrist, we recommend that you turn the crown 15 to 20 times. That helps to ensure that your Favre-Leuba watch has sufficient power reserve and that the accuracy is within the tolerances.
With the movements of the arm and/or wrist on which the watch is worn, the self-winding mechanism winds the movement fully over time. To do this, the watch must be worn actively for several hours a day (approximately four to eight hours, depending on the activity of the wearer).
In diving bells, in which professional divers are accommodated at great depths during work lasting several days, the pressure corresponds to that of the diving depth. The divers can therefore leave the bell without any adjustment time. Once the underwater work is complete, the diving bell is lifted back to the surface with the divers. The pressure level in the bell is continuously adjusted to that of the surroundings.
Now the helium outlet valve on diver’s watches is used in such situations. Under water, the diving bell is filled with an oxygen-helium mixture. During the overpressure at depth, tiny helium atoms from the ambient air can penetrate (diffuse) through the seals into the watch. If a pressure equalization does not take place inside the watch when it emerges – similar to that in the diving bell – the watch glass could pop out. To prevent this, the helium atoms must be released again.
This is done via the special outlet valve developed by Favre-Leuba for the Raider Harpoon. If the valve remains open, the watch is still waterproof for normal use. For any type of dive, however, the valve should be closed.
For the dials and hands of our current Favre-Leuba models we use Super-LumiNova. The Super-LumiNova is charged by daylight or any artificial light source. To ensure the luminosity at night, the watch should be exposed to bright light. Please note that the intensity and duration of the light varies depending on the model. The color of the Super-LumiNova coating also varies depending on the model. For the Raider line we have a blue luminosity and for the Chief collection a green luminosity.
As the gaskets age, the water resistance of your Favre-Leuba watch may be affected. This can happen due to blows to the watch. As described in our maintenance instructions, we recommend that you have the water resistance of your Favre-Leuba watch checked once a year by an authorized Favre-Leuba Service Center. Our watches are water resistant from 30 m to 500 m depending on the model.
Our watches have average rate deviation tolerances of 0/+14 seconds per day.
The accuracy of a mechanical movement depends on the habits of the owner and can therefore vary. A qualified Favre-Leuba watchmaker can adjust the precision of a watch to the Favre-Leuba tolerance.
Favre-Leuba only uses sapphire crystals for the current collection, which are characterized by high scratch resistance. If the sapphire crystal is exposed to a material as hard as or harder than sapphire, scratches may occur.
We therefore recommend that you handle your watch with care and avoid contact with other extremely hard materials.
