Recommendations for
Wearing and Caring for Your Mühle Watch

Watches with a watertightness of 10 bars or above are also suitable for use when swimming, for example all of our Teutonia or 29er models. If you want to wear your watch when diving, however, it needs to have slightly more pressure resistance, with at least 20 bars required according to the standard DIN 8310. Our Sea-Timer BlackMotion and ProMare models have a pressure resistance of 30 bars and are therefore ideally suited for use when doing all sorts of sports both above and under water.

You should also bear in mind that the information on pressure resistance and watertightness provided applies to brand-new watches. The watertightness of your watch may deteriorate over time as a result of knocks or blows and other factors such as solar radiation, contact with cosmetics and chemical reactions with adhesives or paints can also cause its seals to become permeable to water. We therefore recommend that you get the watertightness of your watch checked every 1 to 2 years.

You should thoroughly rinse your watch in tap water after swimming or diving in the sea or pool. We also recommend that you do so after sailing or surfing. Please check whether the crown is in the correct position. If your watch has a screw-in crown, this should be screwed into the case until hand-tight, while a push-in crown should be pushed right into the case. The right crown position 0 is the only way to ensure that the watch is waterproof.

Your Mühle watch feels most at home when sitting comfortably on your wrist, where every motion provides our automatic watches with the required winding energy and your body heat constantly keeps them at operating temperature. If you take off your watch or switch between different Mühle watches every once in a while, you should ideally store your unworn watches in their cases or in a cabinet where they are protected against dust, moisture and direct solar radiation. When storing your watch for a long time, we additionally recommend that you wind it up by hand once a month so that the different oils are always properly distributed throughout its movement.

The power reserve details provided for your Mühle watch are based on the remaining time for which it will run once it has been fully wound. Our chronograph mechanism, for example, has a power reserve of 48 hours when fully wound, meaning that a Mühle chronograph watch can be taken off and stored without being moved for 48 hours before stopping. If a watch does not receive enough energy through motion and is therefore not fully wound, it will stop earlier. You can additionally wind up your watch by hand in order to avoid this problem. You can reach your watch’s full power reserve by putting its crown in the winding position and turning it 20-30 times.

Magnetic fields are not only present in close proximity to magnets, but also wherever an electrical current is to be found. Nevertheless, you can, of course, continue to wear your Mühle watch when travelling on the tram, drilling a hole in the wall with an electric drill or setting your radio alarm clock, none of which will affect your Mühle watch in the slightest. You should, however, avoid placing your watch on surfaces such as the loudspeaker of your hi-fi system or other electric devices or appliances. You should above all be sure to take off your watch before undergoing medical examinations in magnetic resonance tomographs (MRI/MRT scans) because these devices create extremely strong magnetic fields.

If you prefer not to wear your watch during the night, you should try to avoid placing it on cold stone, glass or metal surfaces. Areas that reach extremely high temperatures are also unsuitable for the storage of your mechanical watch. If you want to take off your watch when driving a long distance, you should not place it on surfaces such as your dashboard.
