Frequently asked questions

Where can I find technical details for my Mühle wristwatch?

The most important technical information on watches in our current collection can be found on our website by visiting the “Wristwatches” page and selecting your collection and model. Technical details for your model can also be found in the instruction manual for your watch. If you have any further questions, especially regarding older models, please feel free to contact us.

What precision can I expect from my Mühle wristwatch?

It is normal for mechanical watches to display a certain amount of tolerance because fluctuating temperatures, the tension of the winder springs or the position in which a watch is stored or worn can all affect its operation and accuracy. As we do not know how a watch will be worn, we always regulate our watches so that they are slightly fast, with a precision of between 0 and max. +8 seconds per day. Why? Because we want to ensure that Mühle watch wearers are never too late because of their time measuring instruments.

How often does my mechanical Mühle wristwatch need to be serviced?

Mechanical watches should be serviced from time to time. Over the years, the processes taking place inside the movement cause a certain amount of abrasion due to parts wearing. This abrasion contaminates the oil and sometimes forms deposits, which may cause the precision of the watch to deteriorate. We therefore recommend that our watches be fully serviced every four to five years. We advise wearers to get the watertightness of their watches checked every two years.
