Protect your watch against shocks, magnetic fields, strong heat, water and chemicals and against mechanical abrasion.
Water-resistance according to DIN is a design feature which may be impaired by shock, temperature fluctuations, grease and acids.
Make sure that the crown is always pushed down firmly when you wear the watch.
The leather strap is subject to wear and tear; as a natural product it is particularly endangered by humidity, perspiration, abrasion and chemicals. It therefore has only a limited life cycle and is not covered by the guarantee. The guarantee does also not cover non-metallic straps, such as caoutchouc, textiles or synthetics.
Please have the batteries changed by a specialist retailer and ask him to check the gaskets at the same time.
