The connection between pocket watches and marine chronometers

I have been working for many years as a specialist in the repair and servicing of pocket watches, or "watches" as they would have been known before the advent of the wrist watch. I have been priveleged to work on watches from as early as the late 1700s right through to the 1960s, some of which have been extremely rare and valued for their amazing workmanship.

Finally deciding to collect marine chronometers is a natural progression. In many ways they are the ultimate expression of exactitude in engineering - no expense spared in getting accuracy and dependability in the often harsh environment of sea travel.

Also visible is the hammer for the repeat. Fusee chains are a feature of all mechanical marine chronometers, and serve to equalise mainspring tension
