    MrRoundel reacted to HSL in Roller for 19" Omega Pocket Watch   
    Yes with a quick look at the serial numbers , mine 5543286 and yours 5557368 indicate they are made at the same time period around 1919-1920.
    The movement is not for sale but I can donate it to you. I have a couple more in my stash so I dont have any use for this one.
    If you haven´t changed adress I'll send put it in the mail for you tomorrow.

    I'd be looking to see that the pallet has good "kick" when gently pushed to one side and the other with the balance removed. I'd also check the clearance between the hairspring and bottom of the balance cock. I would also try reversing the balance jewels between the cock and pillar plate. It's amazing how many times those get switched. Not by us, but perhaps any time over the many decades of service. Good luck.

    If i have the parts i am willing to share. I can't use them in a lifetime. And lots of the movements are in bad shape .But some parts look fine. Could be hard to sell if i can't guarantee they are 100% perfect either. So as we all tinker with watches in here and can inspect the parts i send.  It's nice to help out . Some other time it's maybe me that is searching for some hard to find part.

    MrRoundel reacted to bcpitch5 in Hamilton 974 Hands Not Moving   
    I figured it out. I totally overlooked that this particular 974 has the little blue locking screw to lock it in the winding position when out of the case which explains why the hands wouldn't move. I didn't have it locked which kept it in the setting position when out of the case and thus not having enough power to turn the hands....I'm an idiot

    I don't have the tool with me unfortunately but I think all that was there is pictured.
    I think it is just whatever cutting tool that is described in the images that is missing.
    The top part of the Mimo tool is separate to the lower part which is labelled 1CR1, and the top part rotates freely on the base.
    The red balance wheel holders are then placed on the top of the tool.
    The first image in the patent is a vertical cross section through the two parts of tool, illustrating the bearing surfaces.

    I use 3 and 4 jaw chucks, large and small on a "compound lathe".   how does a " bezel - chuck" grab a crystol?  with a 4 jaw,  you invert the jaws and grab the inside so you can cut the outer diameter.   do they make chucks for jewelers lathes?   vin

    that is a wyler style case, yes.  the wyler crystols are unique to this watch AND hard to find.  if you have a lathe,  cut an "aftermarket" crystol to the proper inside and out side to a "press fit" since it is the only thing that holds the watch together.  good luck.  vin

    MrRoundel reacted to manodeoro in Vintage wrist-watch crystals, simplifiable?   
    If your assembly is midcase with rehaut / plexi / bezel then you could the method I use.
    1 - measure the outer diameter of the rehaut and the inner diameter of the bezel.
    2 - search on cousinsuk a plexi with the closest profile, inner diameter a little too small for the rehaut and outer diameter a little too large for the bezel.
    3 - gently sand with 2000 grade the inside diameter of the plexi until you can press it on the rehaut with a tight fit
    4 - remove the plexi and gently sand with 2000 grade the outer diameter of the plexi until you can press it inside the rehaut with a tight fit
    5 - clean everything
    6 - put a tiny bit of grease on the rehaut to help and press the plexi back
    7 - put a tiny bit of grease on the bezel and press it over the plexi with a crystal press
    Using that method I got good results with even 6 ATM waterproofness.

    MrRoundel reacted to oldhippy in Pocket watch barrel bridge and barrel disassembly   
    The correct way would be to let the power down with the correct size watch key, by moving the click away from the ratchet, that is located under the little plate, held by the tiny screws. Always remember with a cylinder escapement there are no pallets, so power must be released first before any attempt is made removing the balance.
    So you have the barrel and the bridge all together. Remove the barrel cape and remove the spring. The barrel arbor should unscrew and become two pieces, and then it will come away from the bridge. Many are not easy to take completely apart, if you find this my advice would be to clean it as it is, you do not want to damage the arbor. You have the thin plate off which exposes the ratchet, that is the part that is going to be the most dirty part and underneath.
    I cannot remember which way the arbor unscrews. Its over 25 years ago for me. Not all arbors have the two holes as in the diagram above. so be careful.

    MrRoundel got a reaction from Klassiker in Pocket watch barrel bridge and barrel disassembly   
    It may have a two-piece barrel-arbor. That means that in order to remove it from the bridge, you must unscrew the sides of the arbor. That's what I had to do do on a Vacheron that I worked on recently.
    When oldhippy wakes up, he may tell you that the arbor has left-handed threads, so be careful, and don't proceed until you know. You can snap the square off the arbor. Sorry to say, but I have done it.
    If you indeed got as lucky as you think you did when you pulled the balance, it was probably because there was very little power left in the mainspring. All's well if it ends well. Good luck with the watch.

    MrRoundel reacted to JohnR725 in ETA 955.114, quartz movements in general?   
    As a reminder you need to pay attention to the data sheet when measuring electrical parameters of watches. For instance to measure coil resistance with the coil attached the meter cannot supply over  0.2 V otherwise the circuit may turn on and give a false reading. The data sheet says anything over 0.4 is unsuitable for measuring coil resistance. Normally when you're buying a meter you not paying attention to this. Occasionally some meters will have a diode symbol indicate though supply enough voltage to turn on a semi conductor device you can test.
    Then I'm attaching a PDF that explains about measuring current consumption. Whether it's an analog or digital meter you need either a capacitor or capacitor and a resistor to basically average the current consumption. When the watch is not driving the stepping motor it's drawing of a very tiny current. When it's driving the coil it's a very short high current pulse and the tech sheets have the average.

    So everyone knows that's interested, all these tools where owned and used by the same watch/clock repair, jeweler that owned the Boley C60 I refurbished and posted about here in the forum.
    Best I can tell he was still in business back in 1979 locally. Of course since, retired, and passed away. 
    As stated, I'm just trying to pass on some little things I managed to aquire that were his tools of the trade.
    Not the Boley C60 though..  that one I'm keeping for a bit. :-) It's a real nice vise.

    You don't need to be a member to join the message board. If you go to NAWCC.org and go to the watch forums, you'll probably see him posting in the European pocket-watch forum. You might then be able to send him a personal message. Good luck.

    MrRoundel reacted to nickelsilver in Hamilton Model 21 chronometer. Cleaning Solution?   
    Tripping can definitely be from the passing spring being in contact too long. It can be from a few other things too. You need to slowly rotate the balance and see the action. The detent should release the escape wheel a hair before the impulse jewel is on center line, then return as quickly as possible well before the escape wheel has finished impulse. It can be a bit of a tap dance between the passing spring impulse jewel and banking.

    I just thought of the fact that I may have seen "Traveler" marked on 1888 models as well. And I just verified this in "The Complete Guide to Pocket Watches".  If yours is an '88 model, I hope you have a case for it. Like the '72 model Waltham, they take a special case.
    If you can provide an image, or at least the serial number, from the movement, the model can be determined. Cheers.
