Members may like to know that a Hamilton Electric Railroad Special watch has, over a continuous test period of more than 18 months,(561 days), gained a total of 4616 seconds.

This is an average gain of 8.2 secs/day - better initial regulation would have improved this figure.
The watch was in one constant dial-up position on my desk.

Humm. If my calculations are correct, the watch gained a total of 57.4 seconds in a 7 day period, and railroad standard was 30+- seconds per week.

Wouldn't take much of a tweaking of the regulator to put that one to standard, and it might have averaged out if the watch was changed in position when timed.

Nice watch!!!
