Majak 11j desk clock, USSR

[leghorn]

Does anyone know if there is a replacement mainspring for this clock. I thought that I read somewhere, that there was one on the market, from one of the supply-houses.
As you probably have discerned,the one in my clock is broken.
Any and all help appreciated.

Am I the only one with one of these desk clocks; if so I guess I will put it on ebay and make a ton of money.
My wife really likes the clock and keeps asking me to fix it. Any suggestions?

What are the dimensions of the spring?

Tinker,
I have removed the spring and laid it aside.Will find it and let you know; do remember that it broke in a few pieces though. I should have it around here somewhere. Finding it should be no big deal, as soon as I do, I will post the dimensions. I remember that it was a open- loop end.

This type uses hook slot mainspring not loop if I recall, I'll check my Mayaks. Came in two kinds, heavy glass and plastic retangular, all 8 days.

Cheers, Watchfixer

Mine is the heavy glass type.
The inter-most coil ends in a hook slot, the outermost end is a open loop.

I found the broken spring. Here are the measurements that I got: Strength: 0.356 mm/ Width: 14.91 mm/ Length: 50".

I can't even find anything close to those measurements in the replacement springs listed at supply houses.

Am sending along pics of spring.

I would probably try Timesavers #16797. You would have to anneal the end and make it a loop end spring, but that's not so hard to do.

 

[leghorn]

Shutterbug, sounds like it might work. After the Holidays I will give it a try.

I have a follow-up question. What would cause the spring to break into so many pieces?

[shutterbug]

I've seen that from a sudden explosive expansion inside a barrel, but never on a loop end spring. It's pretty odd.

I have never seen this on a clock spring, only on watch springs, really odd.

 

[leghorn]

Maybe in the makeup of the then, Soviet steel?
I've seen another one at the chapter 1 meeting, this past Sunday. It was in working order, but no clues where to order another mainspring. I have to say that it was in mint condition on the outside.

Leghorn, how did you separate the bezel from the dial so you could remove the hands to disassemble the movement.
Thank you.

Thank you.

Unfortunately, Leghorn has not been to the forums in almost five years, although he / she is still an NAWCC member.

You may wish to PM ("Conversations") with him directly.

Regards.

 

[Kevin W.]

Rod is your clock like mine ?

 

[Rod McLeod]

Yes it is except it has a blue dial.

 

[Kevin W.]

Remove clock from base, remove winding knobs. Undo 3 fasteners holding the back on. I think from there on its self explanatory.

Hi Kevin. I was able to do that. However, to disassemble the movement I have to remove the hands. To remove the hands, I have to be able to access them. To do that, I have to separate the bezel from the dial. That is my quandry. Tryimg to figure out how to do that.

 

[Kevin W.]

Thanks Rod.I am working 3 days straight, i will try taking mine apart and see how it goes. I honestly cant say for sure, but i dont think its as difficult as we may think it is.

 

[Kevin W.]

Ok, so i was curious. This is where i am at. I pried the metal tabs back around the bezel, got that separated. But isee to get acess to undo the nut holding the hands the crystal needs to be removed. The only thing i can see is. The steel rivets around outside of bezel. Grind them off then that should free the crystal. And then get acess to the hands.

 

[roughbarked]

It is unusual to rivet this. I don't see the rivets in your photos.

 

[shutterbug]

I would be very surprised if anything needs to be ground off. They put that glass in there at the factory, and I'm sure they didn't have to rivet anything in place afterward. It comes apart. Wait for Kevins post. He'll identify the way it should come apart.

[Rod McLeod]

Thanks, Kevin. It had occurred to me that that is how to separate them. It is odd that others seem to have done this task but they are not replying to our pages. I will look forward to your reply.
Rod.

I have not made any more progress since my last post, Rod and others. This clock is not a wasy one to get apart. I will try again later when i get a day off. But i really have not any ideas as to how to get to remove that hand nut and take this thing apart.

 

[roughbarked]

Photos?

 

[Fitzclan]

Looks like the whole thing, after removing the back, may push out through the front? That’s my guess anyway.

Thanks. That is what I thought too but that does not work either. Rod.

Hi Kevin, thanks for keeping in touch. I look forward to your reply when you have time. Rod.
