    Hamilton 917 reassembly...

    I didn't include the pics of oiling the movement as there are quite enough pics already. Suffice to say if you use the 6497 oiling method along with the same grades of oil (found here, http://www.eta.ch/swisslab/6497/6947.html) you won't go far wrong...



























    NB* left hand thread...



















































    I've only done this as a reference for others as there is precious little info out there...

    so cool. thanks!

    tell me, when you say the hamilton is a superior movement to an ETA, what exactly are you praising? i hear things like metallurgy, fit, finish etal...but i'm curious as to how these things make a finer movement.

    The parts are machined much better than any 6497 I've messed about with, tolerances are tighter. The only part of a 6497 that is better imo is the balance assembly in that it incorparates shock assemblies and maybe the hairspring is better too.

    Boy we are getting a lot of wonderful posts!! Thanks.

    ...that's just my opinion and I've been wrong before and will be again and might be now!

    Hi there,

    just two remarks:

    1) Don't touch the visible surfaces of bridges with the tweezers; better grip
    them between a screw hole an the edge. It prevents fine scatches on
    decorated surfaces, and the grip is more reliable.

    2) Prefer screw drivers matching the diameter of the screw heads.

    Regards, Roland Ranfft

    Hello, do you have any tips regarding on how to put the bridge on the right place? i mean, i cant get the gears to fit in the jewel holes, i've been trying for hours, then i give up, then i give it another shot, and nothing.. maybe i have too shaky hands and i won't be able to do it...

    The bridge will find the right position due to alignment pins or tubes.
    But the pivots will not find their holes without assistance.

    Sorry, no black magic, just routine, lots of patience, and very fine tweezers.

    Most troublesome is the last step - the escape wheel. It has the finest pivot
    which has to find the smallest hole. You simply need tweezers fine enough to
    grip the escape wheel pinion from the side.

    Thanks Roland, I'm kind of stupid trying to work on such a small movement ( a caliber 220 from Universal Geneve ). But, that was the only movement i could use at the time anyways...

    Going to try harder, thanks!
