Grosvenor Pocket Watch

Timing Data

I have tried timing this watch using the stopwatch method and I have found that its accuracy is so far below what I might expect of it that I am currently experimenting with its regulator and will report back when I've managed to get a good rate out of it.

UPDATE - I appeared to improve the rate quite a bit by fiddling with the regulator, but then it all went to pot. Regardless of how the regulator is moved, the watch's rate will not now change. It is stuck resolutely at a great many seconds per day. I shall have to take it to a watchmaker.
