In good condition, with just a little wear to the centre on the back. The hinges are fine and the covers snap shut nicely. The back springs open correctly when pressing the button on the pendant. The crystal is fine.
The watch is presented in a mahogany box retailed by I. H. Pattinson of Bradford .
Thomas William Yates patented a variety of slow beat watches between about 1846 and 1880, with beat speeds ranging from 7200 to 11200. This example has the slowest beat, at 7200 beats per hour. The faster beats tend to be later.
The case maker, Samuel Quilliam, was commonly used by Yates. It is very unusal to find a Yates slow beat watch in a gold case (nearly always in silver).
Provenance : This watch is listed in the Fusee Lever Watch by Dr R. Kemp (page 70).
