For the pleasure of the eyes: The original IWC Pilot B UHR.
Love that huge one... Best, Nicolas ...
I got Konrad Knirim’s in 2006
It is 55mm diameter excluding the lugs… A beautiful and interesting watch but virtually unwearable. It is a pure collector. I still have it, I shall take it and bring it out should we have an opportunity to meet in Paris. 😉
My Lange produced and assembled B-UHR with copy of its original papers
History is messy, but unquestionably these are great watches. Bottom pic to show what magic can happen when freedom finally returns ...
