Water Resistance in accordance with DIN 8310

wtr

Applicability

This standard is valid for watches intended for general use.

Designation and definition

Watches which can tolerate the following minimum load are water resistant in accordance with this standard: 30 minutes in water 1m deep and 90 seconds in water 20m deep. For higher loads like, for example, water sport suitability check the graphic displayed below.

Important advice

The, until recently, common description ‘water proof’ was replaced by the term ‘water resistant’ in accordance with an international agreement. Weak spots are the lens, the crown, case backs and even the construction of the case.

Avoid strong impacts (for example, on the lens or the crown). Fundamentally water resistance in accordance with DIN 8310 is not a permanent quality, as the seals are subject to natural ageing and wear.

When the watch is wet or damp, please do not use pushers.

"WATER RESISTANT" is sometimes abbreviated to "WATER RESIST". Always set the crown to the normal position.

Screwed in crowns are often used for watches water resistant from 10 ATM upwards. If this is the case please tighten the crown fully. This way the sealing rings on the inside of the crown will be pressed against the case and will ensure water resistance.
