Hi -

I'm acquiring some Hamilton 770 movements for a project and have so far been striking out in finding any sort of technical information about the movement beyond the usual 22j hand wind etc.

Does anyone know where I can find schematics for the 770? I can work on the movements without these, but it would be much more interesting to work on them with schematics to better understand the movement.

Thanks in advance!

John, I checked the tech. sheet put out by Hamilton for the 770 that's in the NAWCC library and unfortunately it is just a picture of the movement and a list of parts, no schematic. Nothing at all like a modern ETA tech sheet with all the lube points and parts exploded.
