    Hi all,
    I have two vintage Felsa movement watch(with date), they both have the same problem, when the date start to change (around 10:30 pm), the hour and minute hands stop moving, only the second hand clicking. I have to manual set time past 12pm (date complete changed) then the hour and minute hands moving normally.
    Could someone tell me what is the problem?
    Thanx!
    Kevin

    They are probably "indirect drive" meaning that the regular cannon pinion just sits on the center post with out any tension.
    If so, the"notched" set wheel pinion doesn't have any tension on it. What Calibre Felsa movement? can look it up to tell you.
    If they're not indirect drive you just need to tighten the cannon pinion.

    From what I can see on the Bestfit books this is a standard cannon pinion.
    You will have to remove dial and hands,the hour wheel should be free to lift off exposing the cannon pinion.
    Remove the cannon pinion, I usually run a broach through the cannon pinion so that when I tighten it there is less of a chance to tighten it too much.
    Run the broach through the pinion, I use "peer vigor" type "D" cutters to tighten the cannon pinions. Look closely for where the cannon pinion had originally been tightened or adjusted, place the "D" cutter in the same position, with the broach installed through the cannon pinion. Now give it a little squeeze. Not too much, still has to be free enough to set the time. Re-install the cannon pinion only and try setting the hands, if it feels tight enough re-assemble the rest of the stuff.

    If you get it too tight don't try to force it on, just ream it out with a cutting broach. The broach MrBill suggested for inserting in the pinion prior to crimping it should also be a cutting broach, with one of the flat sides resting under where you want to crimp the pinion (it allows a small amount of space for the side of the pinion to collapse into).
