does anyone know where I might be able to source a roller pin jewel for a Waltham 1883 pocket watch at a reasonable cost?

what kind of price range are talking about for a reasonable cost?

then there is the classic problem of things like roller jewels in the Waltham parts catalog for your watch is 1496 is the part number. but typically for American pocket watches for the roller jewel you would go by the size and in this case is a single roller so it would be a longer jewel. So would you know the size of your roller jewel?

Looking to pay around £5 as the watch is to be sold on. I managed to break the roller jewel so the length will be difficult to quantify. The stub is left in the table so should be measurable. I will be looking at an overall loss on the project anyway but have gained some valuable experience along the way (adjusting the pallet jewel depth, lock and guard pin clearance). I managed to improve the amplitude DU/DD from 160 to 240 degrees before my clumsiness broke the jewel.

I hope when you are doing all of that that you also check the banking pins. Usually I find people don't play with the guard pin but people definitely love to move the banking pins because they are movable and of course things that movable easily movable should be definitely moved. then the even easier to adjust on a full plate watch because there they are in plain sight you can move them. As opposed to when they're on the dial side you have to dial off to adjust them on a regular watch. You definitely want your banking pins where there supposed to be before you do anything else.

Oh and if you're using a timing machine remember the lift angle is probably not 52°. 18 size pocket watches can have quite a variation what the lift angle could be.

then it's good that you can measure it because otherwise you need a usually a special tool to measure the slot and the fork to figure out size you need. Then as far as the length goes they typically come in short which is everything with a double roller and the  single roller table there long which makes them harder to find.

      Oh nice. I have a similar wedge style stump for my staking tool, so I'll give that a shot. Thanks!

      Gamblin Gamsol for cleaning?

      By joelcarvajal · Posted

      Thank you all for the replies!  Very informative! True enough, the Gamsol took some time to evaporate and does leave a residue. So not all naphtha are created equal!  Need to find alternatives then. i was able to try Hexane recommended by Alex and it seems great.  I wonder what the cons are?

      Yeah, I saw that in the tech sheet but I don't see how it can be adequately cleaned with the friction pinion still in place. I've accidentally pulled the arbor right out of the wheel once when I used a presto tool to try and remove it. Mark shows how he does it with the Platax tool. Those are a little too pricey for me so I got one of these from Aliexpress and I just push down on the arbor with the end of my brass tweezers. That usually gets it most of the way out and then I just grab the wheel with one hand the and the friction pinion with the other and gently rotate them until it pops off. Probably not the best way but it's seemed to work for me so far.

      Movement inserted from crytal side

      By Zedster · Posted

      Thanks, Jon Sounds like a plan. Obviously I'll have the face on so do you think gripping with the holder will create any problems, but I will check in the morning to see how feasible it is but I assume it only needs to be lightly held. As for holding the movement instead of the holder won't be possible in this scenario as one hand will be puling on the stem while the other pushes the spring down. That was my initial concern is how the hell can I do this with only one pair of hands. All the other times I've had to remove the stem hasn't been a problem, apart from the force required to release the stem from the setting lever, but now I need to fit the face and hands its sent me into panic mode. If it had the screw type release things would be a lot simpler but that's life 😀   Another thing I will need to consider is once the dial and hands are fitted and the movement is sitting in the case I will need to turn it over to put the case screws in. I saw a vid on Wristwatch revival where he lightly fitted the crystal and bezel so he could turn it over, is this the only option or is there another method?

      Main spring

      By nevenbekriev · Posted

      Hi Jon, do You think that relation spring torque - amplitude is linear? I would rather guess that the amplitude should be proportional to the square of the torque. I had once idea to check it, but still haven't.
