Reply To: Waltham Jump Hour

Hi,
I actually got pretty lucky on the dial parts I found. I actually found what you see in picture entitled “with”. There was no drive train at all except for a good balance. Thought everyone might like to see how that movement worked. The 1560 version actually does not have that plate and holds hour wheel down with a dial shim. The 1560d which is the jump hour is the only one that uses the extra plate. What was confusing was that it fit exactly over the other plate so without it having been there in the first place it was hard to figure out what was going on. Makes it fun when you learn something new. My son-in-law brought me one of those Hamilton electrics to look at. Wasn’t a 500 or 505 so I may take a look and start researching.
