My Crescent Street 21j failed, now 10 minutes slow.
Not entered:
The Waltham 15j Model 1879 is 30 seconds fast, excellent time-keeping. I had no idea it was still well adjusted.
The Bunn Special 60 hour, which I got just as the test was starting, is 8 minutes slow.
Both the Crescent Street and the Bunn probably need cleaning as well as regulating; neither having been serviced for many years. Service on the Model 1879 was in 1988.
