Notes

An ingenious escapement probably inspired by the pin-wheel escapement, invented for clocks by Amant and improved by Lepaute but rarely used in watches. Jeune's version of the escapement, which was easier to make that the Amant/Lepaute version, was apparently never used by other makers. The only other watch of this type known to exist is also by Jeune. It is very similar to that now offered for sale, the main difference being the balance cock and the form of the cut-out sectors on the back plate.
