Girard-Perregaux caliber 8381
A while ago, I posted about the Girard-Perregaux Richeville chronograph with caliber 8381. This movement is not inhouse as I wrote, but it is based on the Lemania 1872. David Alstott emailed me this correction and included a nice scan of a Lemania 1872 trio.
You can read more about Girard-Perregaux at WatchRap (by ThePurists), they have a special section for Girard-Perregaux.
