Notes

Note: Fine example of a very rare pocket chronometre made by this eminent maker. Although much inspired by the work of John Arnold, this watch presents an nnteresting compensation balance, developed from that of Arnold, but set with poising weights and timing screws instead of Amold's bolts at the end of the rims.
