Poljot 3133 chronograph

[siralan]

Mainly because I like the look of the movement, but also 'cause I fancied a challenge I recently bought a Poljot chronograph with the 3133 movement.






It was listed as needing a service to correct an issue with the hour/minute hands stopping. 

Having finished my backlog of watches for other people, I decided today was the day to strip it down and see what was what (or wasn't).

I found the reason for the hands stopping:




grrrr. 

And as I continued the stripdown I found another problem




GRRRR.

I also realised at the end that the movement is incomplete - it is missing the finger spring for the minute counting wheel.

OK, so mea culpa on that one. I wasn't familiar with this movement (but I soon will be) so didn't spot this in the listing picture.

These issues aside, the movement is in good condition (I think) and when its all cleaned up and the crystal polished it should run well and look nice.

Tomorrow I'll set about cleaning everything (its been heavily over oiled).





So, I now need to source the parts needed. Worst case this will involve buying a donor.

When I make progress I'll post some pictures.

These Poljot's are good looking chrono's in my book, they're kind of on my long list but if one pops up at the right money.... So I'm very much looking forward to following your progress on this Simon so I can refer to it when I eventually score one.

If I remember rightly, the 3133 is a clone of the valjoux 7734. Would it be easier/cheaper to search for 7734 parts than it would be to buy a 3133 donor?

[rogart]

Cousinsuk have a few parts  for the 3133. Hour wheel was obsolete unfortunately . Must be parts out there . 

[ollie23]

I have the Okean variant dial of this watch. The Russians did an unabashed copy of the Valjoux 7734 for the 3133 movement and mine had a Valjoux part directly swapped into it no probs. Cousins UK for parts.

[ollie23]

If it makes you feel any better my movement had been messed up too. I think the Russian military serviced them with WD40, brute force ignorance.
It means you have a genuine Russian watch when they’re that badly maintained 😜

I'm interested to see the result of this resto, I have been trying to get hold of a Swiss style chrono to pull down and see how they work, trouble is they are always too expensive for my purpose, it would actually be cheaper to buy an Alpha with a Seagull movement than a clapped out Swiss watch.

The Seiko 6319 seem so simple in comparison with the Swiss chrono.

[small]

Those seem to be far more popular on that side of the pond then over here. I sold one I'd gotten in a lot to England, only other interest was from there too. Not a single bite from the sates...

Good luck with the project look forward to your progress report.

I'm a sucker for the Swiss chrono, very much looking forward to seeing this one get sorted.

So it was YOU that outbid me!! :mad: :mad:

I was gonna then send it to George to repair and service. It was to be my first 3133

[siralan]

'twas me.

I was hoping that it only needed a stripdown service but the broken/missing parts look like they will be costly to find. But, its still looking like a good watch is lurking.

I found George's website during my 'research' phase.

I suspect I'll end up buying at least one more of these.

[siralan]

A very generous member on TWF gifted me an almost complete movement and sent it special delivery so I could start work today.

These are the parts I needed




I'm doing a more comprehensive write-up on TWF, but here are some pics of the rebuild to date.


















































that's a very good starting point. 

Next step is the dial side (quite easy I think) and the chrono function (more complicated).

Updates to follow.....

The chronograph driving wheel separates from the third wheel and will allow you to clean the jewel properly. It's a friction fit and it's worth buying one of these if you plan to be working on more of these movements.

[siralan]

Interesting. Thanks for the good tip.

I guess its re-fitted with a staking tool? How do you know how far to press it on?

[pip]

I’ve been through your thread on TWF and wow, that’s what I call a write up. I need to up my game! Joking aside, absolutely excellent write up, probably the best I’ve seen.

I use a hand fitting press although you could use any number of things.

It usually goes back to the same place but you need to check how high it sits in relation to the coupling wheel once all the chrono parts are fitted.

TWF=Thumb wrestling forum?

I had a productive Christmas Eve tinkering.

The dial side rebuild was very straightforward






just look at the thickness of the dial guard - this thing is built like a tank






that was the easy part. Now over to the chrono complication ......






this part of the assembly went without hitch








but getting the operating levers to operate - hmmmmmmmmm








getting to that last stage took quite a few iterations.

The movement still runs nicely






ready to start the rebuild proper








I need to sort out a green lume for the dial batons, and I have one more issue to resolve.

But, its looking good so far.

[ollie23]

Does your watch have any kind of shim to fit between the crystal and the inner rotating bezel?
Mine came with a heavily bodged crystal that was basically no good, once the AM crystal was fitted it developed a rattle which appears to be the inner bezel moving up and down and rattling against the crystal. The thinnest of rubber gaskets stopped the rattle, but also stopped inner bezel from rotating.
In my online research I remember seeing a stripped down one with a very thin metal shim that should be inserted. Can I find one? Can I heck.

[tritto]

Could it use a wavy spring like many of the Seikos with a rotating inner bezel, ollie23? If you could measure up we might be able to suggest one.
