Our S.A.R. Rescue-Timer is a prime example of Nautische Instrumente Mühle-Glashütte and its many years of dedication to manufacturing time measuring instruments that faithfully serve their wearers over a long period of time. In order to ensure that our Mühle watches continue to work as well as they did on their very first day for a long time, even as long as 10 years, we only use high-quality materials and components in our manufacturing activities and process these parts with the utmost care. Nevertheless, in order to ensure the longevity of Mühle watches and their ability to retain their value, wearers also need to take proper care of their watch’s case and movement. You should also send in your watch to be serviced every 4 to 5 years so that its movement can be cleaned and given new oil and other maintenance work can be carried out.
Servicing a Mühle watch
Mechanical wristwatches provide maximum performance every single day. While you may only use your car for an hour to travel to work and the same length of time to return home every day, your wristwatch has to work around the clock. The balance of a Mühle movement completes a total of 691,200 alternations in any given 24-hour period, meaning that it is accelerated to top speed 691,200 times a day and stopped by the escapement just as frequently. These alternations put a huge strain on the movement, which acts as the engine of a mechanical watch. Despite such a strain, a Mühle watch only needs to ‘have its oil changed’ every 4-5 years.
Trust and transparency
As a family business, we place high value on establishing an honest and trusting connection with the people who wear and value our watches. Our customers’ demands and desires therefore form the foundation on which our work is based. Once your Mühle watch has arrived safely at our service workshop in Glashütte, it will be carefully checked by an experienced master watchmaker to identify its service and repair requirements. This watchmaker will then send you a cost estimate so that you can confirm your service order.
Komplettrevision bei Mühle-Glashütte
A Mühle service is like a rejuvenating cure for your watch, both on the inside and the outside. A case refurbishment, for example, can remove any scratches that may be on the case and professionally clean both the watch’s case and its stainless steel strap. Despite the importance of your watch’s appearance, it is, however, a well-known fact that true beauty is found on the inside, which is why our Mühle service particularly focuses on the extensive maintenance of the movement inside your time measuring instrument. Our service aims to return your Mühle watch back to its original perfect condition. In order to achieve this, our service watchmakers carry out a multitude of different tasks:

• Checking the case and strap

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.
