Water resistance classification

Our Watches are classified by their degree of water resistance which follow the ISO Standard 22810:2010 as below.

Water resistance rating


Water Resistant 3 atm or 30 m

Suitable for everyday use. Splash/rain resistant. Not suitable for showering, bathing, swimming, snorkelling, water related work and fishing.

Water Resistant 5 atm or 50 m

Suitable for swimming, white water rafting, non-snorkeling water related work, and fishing.

Water Resistant 10 atm or 100 m

Suitable for recreational surfing, swimming, snorkeling, sailing and water sports.

Water Resistant 20 atm or 200 m

Suitable for professional marine activity, serious surface water sports and skin diving.


Setting the time

To adjust the time of the mechanical wrist watch, carefully pull the crown out. Then you can set the time. Then push the crown gently back into it.

Wind up the watch

Pull the crown clockwise.
In principle, when winding the watch, the crown should only be turned in one direction and proceed with caution. When looking at the side of the watch, look at the crown, turn clockwise, as if closing a twist-lock. In this case, a resistance is felt, the greater the tension of the elevator spring.

If, on the other hand, the crown is turned in the opposite direction, one rotates, as it were, at idle speed. This causes no direct damage to the watch, but unnecessary friction surfaces are strained. Over a period of several years and decades, this may require the tube seal.

Rotate until the mechanical lock prevents further tightening

As soon as a mechanical lock does not allow any further turning on the crown, the spring is tensioned at maximum tensile force and thus fully tightened. The clock can now run with its maximum possible duration. In no case may the user attempt to force the watch to be pulled up again when the device has already been reached. In the case of older clocks, it should be noted that the winding spring may no longer have the same force as a new one and the watch should therefore not ideally be fully wound up.

If you start the clock at about the same time every day, you will get a sense of how many twists of the crown are needed to tension the elevator spring enough. You do not have to pull it up to the stop and leave it less than one turn.
