the 6497/98 movements are great to modify, masters like Dornbluth or Ninchritz make beautiful 3/4 plate conversions, also the specials by Habring and the engraved skeleton watches by Benzinger are truly work of art. These simple and reliable calibers were my obvious choice to base the design on, whe

to Mitch, a truly unique and beautiful watch, how many people can follow the complete building process of their watch, and how many people can become part of someone elses dream? Great story! to Don, on finding your very first customer, can't wait to see your next project; I can only imagine that be

I can only assume that the main objective then also was to get rid of the pushers (be it chrono-pushers

the idea of operating the crono this way is very old, it was originally invented in the 1950's: and actually produced by a firm called Charles Nicolet: the base movement was the then very common Landeron 51 The COS is obviously much better engineered and the system itself is very clever and a bit di

Novoris was a trademark of the Oris watch co; this company still exist, but in the past they made watches (like yours) and clocks with their own movements, afaik these were all with pin-lever escapement, fair quality, but aimed a
