The parts for the wristwatches made by Nautische Instrumente Mühle Glashütte are manufactured on CNC machining centres, which produce the parts that we design to an accuracy of one thousandth of a millimetre. Even though MÜHLE are extremely proud of all the skilled manual work that goes into the competition of the parts and the manufacture of MÜHLE watches, without these machines they would not be able to maintain the high quality standard. These machines supply High-precision blanks.
As a small, independent family business MÜHLE adheres to the stringent quality criteria of craft manufacturing. This is most obvious in the finish and assembly of the watch mechanisms they use – all work is completed manually.
After a mechanism has been completely assembled, the woodpecker neck regulation is used for exact setting of the rate. This regulation is carried out in six different positions, through which MÜHLE simulates every possible wearing position on the wearer's wrist.
During regulation, time which the mechanism gains or loses in all six positions is measured using a timegrapher.
