Mühle-Glashütte watches are made in Germany by a company who specializes in “Nautische Instrumente” – nautical instruments and timekeeping systems for ships. It measures 42.5 mm across and 11.5 mm tall. The case and bracelet are all stainless steel.
In all honesty, this is the first time I’ve heard about this company. I could easily mistaken this watch to be a plain chronograph.
