Water Resistance

WATER RESISTANT (in German: Wasserdicht)


Water Resistance Table:

Each watch carries indications relative to its rated water resistance and capacity to face humidity and contact with water.These indications on the rear of the watch casing will consist of the term "water resistant", generally supplemented with a quantitative indication expressed in meters (MT. 30,50,100, etc) or in atmospheres (bar 3,5,10. )


Water resistance (3 bar)

if "WASSERDICHT 3 BAR" (WATER RESISTANT 3 bar) is inscribed on the rear casing, your watch is designed and manufactured to withstand up to 3 bar, such as accidental contact with splashes of water or rain, but it is not designed for swimming,taking a shower or bath,or for diving.


Water resistance (5 bar)

if "WASSERDICHT 5 BAR" (WATER RESISTANT 5 bar) is inscribed on the rear casing, your watch is designed and manufactured to withstand up to 5 bar and is suitable only for surface swimming.Competitive swimming should be avoided as variations in water pressure may exceed the 5 Bar rating (*See further explanation below).


Water resistance (10 bar/15 bar)

If "WASSERDICHT 10 BAR" (WATER RESISTANT 10 bar) "WATER RESISTANT 15 bar" is inscribed on the case back, your watch is designed and manufactured to withstand up to 10 bar/15 bar and is suitable for taking a bath, shallow-diving, but not for scuba diving.


Water resistance (20 bar)

For scuba diving we recommend that you wear a dedicated divers watch (20 bar).



1. Before using the water resistance 3, 5, 10, 15 or 20 bar watch in water, be sure the crown is pushed in completely.

2. Do not operate the crown and the pushers when the watch is wet or in water. If used in sea water, rinse the watch in fresh water and carefully dry it completely.


Watches are tested to withstand water pressure in a LABORATORY setting.

For example 50 Meters water resistance meaning : tested in the laboratory under ideal conditions (i.e.. MOTIONLESS) withstanding a pressure of 5 ATM under water (i.e. water used in laboratory at a certain temperature). Obviously these conditions are never met in a real swimmer's or diver's circumstances due to movement: Water in rivers,swimming pools,seas and lakes,will contain various levels of chemicals,salts,and other minerals.Swimming pools may also contain chlorine,ALL these caustic materials can potentially weaken/damage a water seal or sealant compound in a watch and cause water pressure changes due to density etc.Change in temperature (warmth-and-cold) while showering can also cause water ingress to the watch casing.

In sports swimming,the movement of the wearer's arm through the water increases the pressure on the watch dramatically.Whether in the swimming pool,washing the dishes or taking a shower,your arm may move swiftly,which can increase pressure substantially.A simple shower,depending upon the strength of the water jet can also expose the watch to a higher potential water ingress pressure than rated in the Laboratory.As mentioned,the simple act of immersing in hot,then cold water can cause substantial pressure variations.You must also consider that over time chemicals may deteriorate the gaskets,seals,and sealant compounds.The same applies to subjecting to hot and cold air in quick succession.

Remember,we want you to enjoy your watch.It will give you many years of service if it is looked after properly.
