The movement of this clock is that of a standard Mercer eight day chronometer. The case, however, is a prototype designed by Tony Mercer and produced in the Mercer workshops. The hole to the side of the case with sliding cover (matching the one to the rear) was put in place with a view to the possible implementation of a side-winding system. The clock was assembled by Tony Mercer and did not go into production.
