Here a few pics + a vid of the ships clocks. Both movements were identical Smiths but I could only get one of the platforms to run successfully (so far). However the customer only wanted one returned which had the readable dial. 

Both clocks I found with the same fault with the mainsprings that had been wound so tight they had ripped the end holes. Although I could have repaired the springs I purchased a new spring. A very simple movement with platform escapements so a straight forward repair/ service.

However worth noting I cleaned the platforms by running them through my watch cleaning machine first and then stripped the platforms removed the jewels and soaked in a degreaser. Despite this under inspection with my microscope there were still significant and stubborn deposits of dried oil on the jewels so further rubbing with pegwood was required.. The runner had to be set on almost max gain to achieve good time. I did notice this how it had been set before so perhaps the h/s is a touch short. 77F96A63-5DB8-4BDE-8EE1-452A670873A7.thumb.jpeg.0fb4a70770225b03e098b0920e5ea9c0.jpeg

Cleaning the cases one completed. Used Priory concentrated cleaner followed by liquid brass.

Overwound indeed 😒

Very simple movement being assembled

Not bad little movements. What is wrong with the other platform?

I really don’t know at present. Under a microscope I can not see any obvious faults.  The meshing between the escape teeth and the escape wheel pinion seems tight or even binding and it was the platform that showed no life before stripping..  I will have to have a play..After cleaning and lubrication this platform run really well and free with just puff of air so the area I suspect I will investigate first.

    • I have acquired a Citizen Leopard 36000 watch. My reason for purchasing it was my desire to own a timepiece with a 36,000 BPH movement, and the price was reasonable. Another motivating factor was gaining hands-on experience with the mechanism. The watch is in good condition, but I intend to fully disassemble it for maintenance. First and foremost, if anyone has prior experience with this particular model, I would greatly appreciate their insights. I do not have access to Citizen’s specialized lubricants and will need to use the ones available to me, such as 9010, 8000, and 8300 grease. Additionally, I do not possess the appropriate oil for the pallet jewels and will only be able to clean them.
    • Hello all, I am working on an older Valjoux Chrono. It doesn't have a stamp on the movement anywhere but I believe it is a Valjoux 72. I installed the train of wheels and they will not turn. The problem appears to be the 4th wheel and the escape wheel are not interfacing correctly. I had to replace both of these parts as the pivots were broken on each. I sourced genuine Valjoux/ETA replacements. I think the problem is with the escape wheel as all the wheels turn perfectly if I remove just the escape wheel.  My question to those with more Valjoux experience is am I mistaken? Is this some other model altogether and I have the wrong part or parts?    
    • I would remove the wheels, check for damage and if not damaged, clean. 
    • Thanks for the replies! Here's a photo of the front of the clock and a GIF animation of the movement (exposed by removing the black cap in the centre of the clock). You can see the behaviour of the gears. It's a fairly valuable clock from the 80s (Braun ABW 35). I'm not sure if replacing the movement would diminish the value, so I'd prefer to keep the original parts if it's easy to fix. But since the movement itself is pretty generic, I guess, maybe replacing it wouldn't make any difference with regard to the value of the clock? Or would it? I suppose the value is mostly in the design.
    • Well, my fundamental stance is that I want to go in and out without leaving any trace other than a shining, perfectly running movement. So, no scratchings on the inside of the case back lid, no marred screws, no debris, no fingerprints, and so on. That is, my goal is to make it impossible for the FBI to track me down. As a professional, I suppose you might want to keep track of returning watches, but as @JohnR725 mentioned, we can keep detailed computer records without marking the watch at all. That may not be true for every watch, but luxury and COSC-certified movements do have unique numbers. John also says it’s best to leave no sign you were ever there, and I couldn't agree more. Now, suppose the Sea-Dweller I'm working on is one day scrapped, and you want to sell the case-back separately (perhaps the case was destroyed in a plane crash). Then the scribbles on the inside no longer reflect the current movement inside the case. Also, the engraving will likely halve the market value of the case back. It had been "sleeping" for about a week and a half. Yes, the "debris/old lubricant" theory is my hypothesis as well! It will be interesting to see what I find once I have time to start disassembling the movement.
