= Protected in everyday life, bathing, accidental splashes, short swimming or car washing - it is resistant against perspiration, water vapor, rain drops.
It is tested for water resistance up to 3 ATM, and must be able to survive 30 minutes under water at a depth of 1 m (3 feet) followed by 90 seconds under a pressure corresponding to 30 meters.
WR 50m / waterresistant 5 ATM / 165 feet
= Protected in everyday life, bathing, accidental splashes, short swimming, car washing, parachuting, hang gliding and skiing - it is resistant against perspiration, water vapor, rain drops.
WR 100m / waterresistant 10 ATM / 330 feet

= Protected for professional scuba diving with scuba gear and all kinds of water sports to a depth of 50 meters, for 2 hours.
The metres value does not relate to a diving depth but to the air pressure used in the course of the water resistance test, DIN 8310, ISO 2281, NIHS 91-10. Therefore please carefully read manufacturers instructions before „in water use“ of all ladies or mens watches bought from yellowatch.
We recommend to have your watch tested annually by one of our authorized yellowatch service center’s, especially before summer holidays.
