I just finished overhauling a 6F movement. Before, it was running very fast, and the Timegrapher couldn't get a reading. After going to the spa, having a nice oiling and a 12 hour rest on the Timegrapher it showed numbers of +/- 5s/d, 230 degrees amplitude, and 0.3 beat error. For a movement this old, I'm happy with that!

Oh, and yes, obviously there is a balance and pallet fork which were removed for the picture! :-)
