I have got my hands on a Vulcain Wall World clock, which is to be hung up in the workshop. However, there are some challenges. More second hand are missing, so i have

to find someone who can fit?  I think the easiest thing is to change them all.  Since the watch is from the USA it is 110v so I also have to convert from 230v to 110v!  An alternative is to switch all drives to Quartz.  What would you do?

Show us an image of the back.

Converting from 110 to 220 is a transformer...pretty simple.

No, do not convert to quartz.  By staying with the current movements, all of the second hands can be synchronized.

Lastly.  This is a whole lot of trouble to go through and there are better ways to spend your time.  Just send the clock to me and work on more important projects 😉

I am uploading some pictures of the back, but right now the clock is on its way from the USA to Denmark. Yes, the easiest is probably to find 5 new second hands or possibly just 4. The volt reduction is as you write quite simple and I do not think such a watch has much power consumption?

I'm not sure what kind of movement the clocks are using. But if they use AC synchronous motors, then it will not be as simple as using a step down transformer because the mains voltage in Denmark is 230V 50Hz. American voltage is 110V 60Hz.

That's the reason why I can't buy AC clocks from the US. But I was told that there is a step down power supply with a frequency converter. I'll try to find the name of the company that sells it.

You could purchase a US UPS battery backup (APC makes a purse sine wave version).  Power it from a transformer that drops 220 to 110.  Maybe APC makes one with 220 input...dunno.

A lot of money to make it go.

Perhaps something like this will do. Instead of the shown power supply a supply for Alarm can do it and then a 12VDC bly battery can be added. But still a lot of money.

Can't wait to see how this turns out.  I was looking at a vintage clock motor on ebay this morning.  It was rated at 3W, so if this is close to these clocks, you might need 15W to power the whole thing.

    • 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.
