Notes

This is an excellent example of the final development of Motel?s chronometers, with the final shape of the fusee curve, the isochronous conical balance spring, and a superbly finished escapement with curved studs, jeweled and capped balance and escape wheel, with ruby locking, unlocking, and impulse jewels.
