The Basics

By introducing the “R. Mühle & Sohn” manufacturing line, the company is now writing yet another chapter in its 145 years of history. This is above all owed to the mechanisms: the Robert Mühle calibre models were all designed in the spirit of classic Glashütte watchmaking. As a result, these Mühle movements are the first to sport an engraved balance cock and colourful screwed gold chatons. Reference M1-11-05-LB has a silver dial and is fitted a black crocodile leather strap
