    Can anyone tell me the date and what is missing at the base of this Zenith chronometer? It has a hacking device at the base which is a very small screw that I have taken photos of and there is some kind of spring also at the base. The clock is top heavy, so the dial turns downwards when it is in it`s gimbel, Should there be a weight at the base to stop this? Many thanks, John

    Most of these deck watches were put in similar cases with a weighted bottom section if mounted in gimbals. The American examples from Elgin, Waltham and Hamilton all have essentially the same form.

    Attached is a picture of the outside of a tub containing a Jurgensen pocket chronometer that was converted for military service at the beginning of WWII by the Roth Brothers.

    Thank you Mr. McIntyre for the information on the weight for Chronrmeters. Would you know where I may find information on the hacking device that would have been at the base of this Zenith. John
