I just purchased this Waltham pocket watch ($10)  Would this watch be an early 1900s or late 1800s pocket watch. I am about to service this movement. Could this be an W.M. ellery movement from the late 1800s. Its 15 jewels the serial number is 20358779.

Come to Alberta Canada. Edmonton Old Strathcona. Many old buildings from the 1890s and early 1900s. Lots of old train stations still standing. Most of these relics end up in the old Strathcona Antique mall. Second biggest Antique mall in Western Canada. The CPR rail juction still runs through this area since 1905. The Strathcona hotel built in the late 1880s still stands and is still used to this day. Lots of watches and clocks working or non. Sell for chump change at times.

FWIW, I believe that this is a pretty late serial number for an 18s '83 model. By 1915 most were probably opting for a 16s, or even 14 or 12s over the larger 18s. The nickel silver/silveroid/silverode case is about as sturdy as they get.

While you probably already know this, you must be very careful about separating the plates, as the pallet-fork commonly hangs up, resulting in a broken pivot. There are many 18s, full-plate watches that are in the boneyard because of broken pallets. Good luck with your Waltham. Cheers.

The "trick" to most full plate 18s watches in disassembly and reassembly is to do it upside down. Once you remove the balance and mainspring barrels, remove the plate screws and invert the movement in your holder. Carefully separate the plates, teasing the pivots from the jewels/pivot holes. The pallet actually sits partially inside the lower balance jewel cock. Reassembling is the reverse process.

If you look around the dial end there is a little slot with the edge of the click sticking out.( movement out of case)  Turn the stem gently until the click moves a bit slide it to the right and while holding the winding stem let it down slowly. Also it's good to remove the dust ring. Don't let it unwind to fast or you could damage the spring or it comes off the arbor.

I have to ask, how do you let down a full plate watch?  I see the barrel but how do you get to the click?

there is normally a lever or slot near the barrel on the dial side plate that you use to let down the spring. Otherwise you would simply remove the dial first, insert a bench key and put some tension on it, depress the click and slowly let it down. If there is a slot, or sometimes it's just a hole, you insert a needle or the like, put the tension on the winder, and press, then let the spring down. Each manufacturer had their own system, and some had several types depending on the model.

I use a piece of rodico to stick the pallet fork to the upper plate, then remove it after assembly. I do a lot of pocket watches.

Has been going good so far now.  Still running very smooth. Taking it apart. I lifted the plates ever so slightly using Rosinol lighter fluid, to clean the pivot holes and a toothpick to clear out the dry varnished oil and kept slightly working it until the top plate came off and lifting it slightly sideways so the pallet fork didn't catch on the bottom balance jewel cock for there is a cutaway so it doesnt catch. Serviced the watch relubed it reassembled and it's been running good for over a few weeks now ( after winding it a few times). It actually keeps decent time.

      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.
