Changing time and date
Make sure that your watch is perfectly dry.
Move the crown carefully to make the various changes that are possible.
Avoid changing the data between: 8:00 pm and 4.00 am.
Once the changes are made, push the crown back in and (depending on the model) screw it down against the case to preserve its water-resistance.
Airport Security check
Before going through the metal detector we recommend you remove your watch and pass it though the hand baggage scanner. Watches are sensitive to the magnetism produced by the metal setector.
In humid environments
First make sure you watch has passed a water-resistance check during the last 12 months at a authorised service centre.
Check that the crown is fully pushed in (and screwed down, depending on the model) against the case in order to preserve its water-resistance.
We recommend that you prevent the leather strap coming into contact with water to avoid deformation or discoloration.
For frequent or prolonged use in water, we recommend a metal bracelet or a rubber strap.
After each exposure to salt water, rinse the watch carefully in fresh watter then dry it.
The table below below indicates recommended activities according to the water-resistance of your watch. Theses figures are indicative only and do not correspond to a maximum depth of immersion.

In cold conditions
When in cold environment we recommend keeping your watch on your wrist so that it remains close to the body temperature. Below 0 C (32 F) the lubricating oil in the mechanism can lose fluidity, which risks damaging the movement.
In strong sunshine
We recommend avoiding direct exposure to the sun’s rays because of temperature of the watch can rise above 60 C (140 F). This risks damaging the movement.
Prolonged exposure to Ultra Violet rays can alter the colors of some parts (leather straps, dial etc.)
