Mühle Glashütte Watches

Authorised retailer for Mühle Glashütte Watches. Mühle Glashütte watches are known for being some of the most precise on the market today. The German company focus on producing watches with fantastic legibility and accuracy. Mühle Glashütte have always ensured that accuracy and functionality remains paramount in their watch design. They are known for creating practical, clear and functional watches rather than focusing on fancy decoration. This has allowed them to constantly produce a range of high quality Mühle Glashütte watches which are perfect for everyday wear.

The History of Mühle Glashütte

Mühle Glashütte can proudly claim to be the only watch manufacturer in the town of Glashütte which is still owned by a local family. The company was founded by Robert Mühle in 1869 and the Mühle family has lived in the Glashütte region for over 700 years. The family has also been active in the watchmaking industry for five generations. Robert Mühle initially produced precise measuring instruments for watch manufacturers in the area before moving on to the production of speedometers and rev counters. Over the years the company has shifted towards the production of wristwatches, which they are known for today.

Functional and Precise

Mühle Glashütte watches have always been defined by functionality rather than beauty. The collection includes a wide range of high quality watches which are understated and perfect for everyday use such as the Mühle Glashütte 29er Zeigerdatum Synthetic Band White Dial . It is fair to say that Mühle Glashütte watches are some of the most precise mechanical watches that you can buy today. Thanks to this reputation, build after 147 years, the Mühle name will always be linked with precision.
