The independent Glashütte manufactory Moritz Grossmann brings a piece of history to the ninth Only Watch benefit auction with a superbly crafted, unique timepiece. The auction takes place on 6 November 2021 in Geneva.

Moritz Grossmann is supporting the non-profit association for the third time and has again crafted a truly unique example of Glashütte watchmaking.

The dial adds to the undeniably elegant appeal of this unique piece of jewellery. It boasts a silver-plated by friction technique painstakingly finished by hand, a traditional art that ensures the time display can be read easily at all times and perfectly complements the distinctive appearance.

Another splendid statement comes in the form of a solid gold balance cock, elegantly catching the eye in the highly finished movement.
