Case back engraving:
• 3 ATM: the watch resists to accidental contact with water and normal perspiration.
It means no immersion in water, neither for swimming nor aquatic sports.
• WATER RESISTANT 5 ATM: this watch resists to occasional immersion.
An annual control of the sealing gaskets is necessary.
• WATER RESISTANT 10 ATM: the watch is suited for all aquatic sports, except diving.
An annual control of the sealing gaskets is necessary.
• WATER RESISTANT 20 ATM: the screwed crown, the thickness of the crystal and packings have been especially
designed to withstand pressure of 20 atm. Make sure that the crown is entirely screwed, before you go into the water.
An annual control of the sealing gaskets is necessary.
