    Other PW Gruen "music" pocket watch with Reuge music box

    RJ- I'm familiar with all the variations you note above. Won't have a chance to get at the watch for a couple of weeks. In the meantime, has anyone else actually opened one of these?

    Other PW Gruen "music" pocket watch with Reuge music box

    Thanks. I already unscrewed the winding key and removed the switch knob. I'll try a case knife on it and see what occurs.

    Other PW Gruen "music" pocket watch with Reuge music box

    I was recently given a relatives Gruen pocket watch. It has a built in Reuge music box which I believe is mounted on the watch back. I would like to know how to remove this particular case back. It will screw about a third of a turn and stop . I am reluctant to put too much force to it lest...

I suggest you search dial...

    What adhesive for gluing loose seconds bit back into a pocket watch dial

    No need to heat the dial the way I do it, Tom. I use flake shellac dissolved in denatured alcohol. You brush it on, hold the 2 parts up to a 100 watt bulb and it sets in about a minute. You can reverse it by putting the dial in alcohol for a couple of minutes - no heat needed. I don't guess...

    Overbanking-cause & correction?

    All the prior input is dead on. And it sounds like you did everything right. Let me add 2 things to consider. I have several watches that keep excellent time in all positions but go wonky when carried in a pants pocket. They stop erratically or lose time. Outside the pocket they run fine and...

    Is there a substitute for shellac?

    there are different ways to use shellac. if you use it the old time watch maker way - either in flakes or threads - it takes a lot of practice to get neat and proficient with it. Here is another way to use the same venerable traditional substance that is much easier - use as a liquid. You...

    hair spring help

    it looks cupped to one side. maybe it might correct itself with the spring between the regulator pins. or else a kink somewhere has it put it off to one side. once you get it free, study it against a white background - makes it easier to spot.

    A common watch symptom - what might it mean?

    Got it. Thanks, Karl. The watch is such a dynamic machine and I keep applying static analytics to it. Going to go stick my head in running water.

    American PW Removing a plate jewel

    A photo would be helpful. It sounds like you are dealing with jewels that are burnished in. In that case, the reccomended tool is a jewel setting opener, which sounds like what you have. They ususally come with several tips to fit different size settings, which would address the problem you are...

    A common watch symptom - what might it mean?

    Just a visual based on the escape wheel - does it have a little bit of reverse motion when the train runs down. I read that was a measure of the train being in good shape.

    Decreasing amplitude with increasing winding

    Not that, but similar with an American 16s movement with a spring that pushed up against the barrel cover. The tighter it was wound, the worse it ran. As the spring ran down, it began to run better, best was about the middle of the wind.

    A common watch symptom - what might it mean?

    Guys - thanks for the input. I already understood that it was resistance. Now I'm understanding that if the train runs smooth up to the pallets without the extra pressure on the crown, and doesnt run when you put the balance back in, the problem must be in the balance, jewels, or hairspring...

    A common watch symptom - what might it mean?

    I have had several movements that run with poor amplitude, but if the mainspring is fully wound, and you give the crown another little twist, tightening the spring a bit more, then hold the crown there, they take off and run with a good swing. Until you release the crown. I've seen this in 2...

    What to do if you lose a screw (NO JOKES)

    In the old time watch schools - Elgin and Bulova - the first thing they did was practice putting a bunch of screws into a container, taking them out, putting them back in. Not a bad way to start. As well as the suggestions above, some people use a bench apron or catch draw - the first a...

    Some Questions on a Waltham Grade 636

    Actually, that jewel is not capped. It's a single jewel, a hole jewel with a raised jewel setting. I guess it's screwed in from the bottom because the setting is too high to allow for screws on the top side.

    Other PW Hair springs

    I have the sewing needles, but the thanks for the tip with the tweezers. All the bends I made with tweezers always had a small crimp in them, which I would try to smooth out after. The 45 degree tips might solve that.

    Other PW Hair springs

    As a relative newcomer, hairsprings are my nightmare. While I have managed to straighten out a couple, I have mangled many. I've also found that replacing hairsprings, even when you use one from the same exact make, grade and model is not straightfoward. I believe each spring is vibrated to the...
