Cannon Pinion Help!


Question

hello guys, been a while but I have a movement that is really starting to get the best of me. problem after problem then finally when i got it all together and thinks its good to go I realize the hands are not moving even though watch is ticking away......now I know what your gunna say "loose cannon pinion" well no if anything its seems too tight. Its stiff when changing time from the crown, i checked each wheel separately and doesnt seem to be any binding until i put the canon pinion and the wheel that moves the canon pinion from the stem (whatever that wheel is called drawing a blank). I really dont get it, I have tried it with 4 other pinions and still no dice. I dont see how a tight cannon pinion would stop the time from advancing. iam thinking about replacing the center wheel but not sure what that will do since i tested the train before installing the pallet fork and balance and its as smooth as ice. BTW its a waltham 1907 7 jewel 0s movement. any ideas.

I don't suppose you're trying to run the watch like you normally would without the case?

This is where it be helpful to have a picture for everybody not familiar with American pocket watches? a problem with American pocket watches is, when the movement is out of the case the case has the crown and stem. The movement then goes into setting and if you try to run the watch out of the case in the setting position it doesn't always run. Sometimes the run fine but they're still driving all the setting mechanism.

Later on the watch companies grasping that they had a problem put a variety of ways to put the watch basically into a service mode which is basically put it back into a winding position out of the case. I could make a variety of gases where it is but it be helpful if you give us a picture or several. Like a side picture where the stem goes and would be helpful and the front and the back.

then as it's an American pocket watch and they have parts manuals showing all the parts just because they exist swapping them is not a good idea. The catalog may show interchangeability but often times the parts were fit for that particular watch. So if you start swapping parts you can end up with all kinds of interesting and strange issues. Always best if you can keep the original parts with the original watch.

Obviously, cannon pinion is not your problem. Please read JohnR725's comment above. In particular his "without the case" point. I do not know if you actually have the watch case, and if you do, did you alter the Sleeve (removed it for cleaning, etc?). That could be a part of the problem also and you need to simply adjust it.

    • There is a Orient movement too, HFA00, but it's even less common than the Y182B.  The 7T42B will also fit and work fine too, but it's less common than the 7T32B. Physically, many other Seiko movements, 7T52, 7T34, etc. are the same size and shape.  But the hands and date are different, so they wouldn't make sense with your dial. So how frakenwatch do you want to go?  I think ANY 7Txx movement can fit in the case.  The part that matters is getting a spacer ring that fits the movement to the case's diameter.  But this is just a plastic ring and one you have could probably be easily modified to fit another 7Txx.  The two crown and three pusher layout of the 7T32 is less common.  If the donor movement has a different arraignment, it will be rather ugly to say the least.  But at least the main crown will always be there at 3 o'clock so the time can be set! The dial itself needs to fit the case and there is usually a bezel ring meant to fit the dial and case.  Thickness is an issue too with the bezel ring fitting the case.  However, these don't really come in that many different sizes. But you might be able to repair your watch.  If the circuit board has not been damaged then the remaining parts are attainable.  The exact correct crown might not be available, but one that fits and looks close will be. And if the circuit board is damaged, then you can buy a working watch to get the movement or board.  That's much easier than trying to fit a 7T92 into your case and will have a better outcome.  
    • Hi      The Empire models were made by the Anglo/Celtic Watch Company in wales from 1948 1980   https://www.smithswatches.com/pages/smiths-guides-2                                                                 https://www.smithswatches.com/pages/smiths-guides-2 these two sites contain quite a bit of information. Does the watch have a serial number on the back.  The movement will have some identification on the front plate under the dial or under the balance wheel.
    • Hello and welcome to the forum.   Starting out on the right fool Via Mark's courses well done.
    • Hello all,  I just completed the first stage course and enjoyed it very much , I have a small collection of manual watches and a fair number of Royce watches all now going bar one, a small ladies pendant fob watch, - was told it was overwound? I know ! I know! - buy will wait till course two completed before I get confident with that one, I have been looking for a unitas ETA 6497 movement, and was horrified at the prices being asked on ebay and Amazon, anyone else struggle with this.  as I write I have found for 42 pounds plus postage which I will take and use after to build my own watch. how weird I start writing about ot then found one! keep you all posted    Alan
    • Any Smiths Watches experts out there who could help me date this watch? I know it was made in Wales but would love to know it’s age. Thanks.
