Antique MINNEAPOLIS-HONEYWELL THERMOSTAT PROGRAM CLOCK 1924-34 8 Day 7 Jewel Honeywell's Model 77 was a best seller from 1924 to 1934. It had a wind-up mechanism that was replaced by the electric clock in 1934. The Model 77 was named for the number 77 on the jersey of the great halfback of the Illinois football team, Harold "Red" Grange. I have not tested this clock. It needs a key to wind it and it is not with the clock. It does tick when I hold the button down in the back. 

It is in Great condition with no rust.
