Marc Brogsitter was a
German lawyer and
watch collector who was passionate about
shaped wristwatches from the
1940s and
50s, those from Patek Philippe in particular.
In the early 2000s, he decided to create his own brand and started a collaboration with a talented young watchmaker working at Gübelin at the time, Karsten Fräßdorf (who eventually started his own brand, "Montres KF", in 2016).
Their collaboration didn't last very long, unfortunately, but they nevertheless created, with the additional help of Urs Gottscheu, around ten watches, powered by two different "in-house" calibers which were each cased in two different "in-house" cases.
1) The two calibers:
- Cal. 793 (or 794) Tourbillon
- Cal. 793 (or 794) Constant force
2) The cases:
- Rectangular with straight lugs
- Rectangular with fancy lugs & faceted crystal
Let's have a look!

Do you like these watches?
I personally like the idea a lot and I prefer the straight lugs case, but these timepieces seem to be a bit oversized: thickness and lug-to-lug are too big. I would much prefer a smaller case.
Thanks for reading.
