Hey guys, I'm doing a project where I need an Omega 861 (or any 3 register Lemania 1873 based movement) but they are near impossible to find. I would settle for a Lemania 1873 but they are also difficult to find. Does anyone know what other manufacturers used the Lemania 1873 as a base movement? I know Brietling did in their B12 used in the Callisto and Tissot's 873 used in the PR516. Others I'm aware of are Paul Picot but that's about it. Any help would be greatly appreciated.
