ABOUT THE WATER RESISTANCE OF YOUR WATCH?
Our leak test of a watch using a Waterproof Tester
First of all, we check for each watch, after assembling, its waterproofness.
Thus It is a question here of attaching the watch to the bottom of the metal rod (see photos). Then we fill the tube with water. We then replace the dome-shaped cover on the tube and pull the lever to increase the pressure up to the desired value (5 ATM), then wait 3 minutes and Finally we immerse the watch in water. If air bubbles come out of the watch (what you can see in the water) is that it is not waterproof, otherwise your watch is totally waterproof.
This system is extremely reliable, because, any slightest leak can be seen right away.
All the means to preserve the water resistance of your watch according to its water resistance degree:
It is imperative not to wear a watch in saunas, hammams, showers, baths, in order to avoid deterioration of the seals due to high temperature.
Rinse the watch in fresh water after each immersion in sea water to prevent salt from damaging the seals.
Remember not to touch the buttons or crown of your watch while it is underwater. Check that they are well inserted or screwed in.
Waterproofing table : All GRIGRI watches are water-resistant from 50 to 100 metres. Check the information on the back of the case of your GRIGRI watch and read the waterproofing table below carefully.

Waterproofing guarantee :
the waterproofing of your watch cannot be guaranteed for life because the seals can wear out, the crowns or push buttons can be subjected to shocks and the climate or temperature can change.
