You may remember Grandpa's watch from previous instalments. A modest man's pocket watch of the 30s, other than Chris Heal's service, it's not a fettled or specially prepared racehorse in any way. Not exactly Kew, but, I decided to put its recently serviced movement through its paces in my own lab in my own version of the 'Observatory Trials'.
An Everite from 1937/8. Not exactly Patek tourbillon material. We'll see. Go baby go!
So far so good. Day 3 and so far the mean deviation in rate is 0. Whooh hoooh! Stay tuned for ongoing updates. (Beats reality TV anyday.)
