poljot alarm cal 2612.1

Hey

Any one familiar with this watch?

This is the bottom of the 2 center wheels. Is this supposed to connect to the alarm mainspring barrel?

Yes i took pics as i stripped but missed this bit.

cheers

I'm pretty sure that those two aren't supposed to mesh.

The alarm mainspring barrel should mesh with the alarm star wheel pinion.

So why the hell wont mine.

Hi

Yer that.s the problem my watch is a 2612.1. i have the tech sheet for the 2612 but are they the same?

Cousins say they do not  have a part i require for the 2612.1 but they do have it for the 2612.

Also ranfft say they are both based on a AS 1475 but then the part numbers are different.

What i really want to know is my watch the 2612.1 the same as the 2612 0r the AS 1475. 

Or are all different.

I am just hoping someone has had a similar problem before and may be able to point me in the right direction.

cheers

They look virtually identical, (all be it that the balances in the three examples on Ranfft are different, but this is probably simply down to manufacturing variations over time).

The stem, dimensions, mainspring, bridges etc look the same.

Are the alarm and time barrels the same dimensions?

[gary17]

No they are different sizrs

[Marc]

If the one that you've installed in the alarm train doesn't mesh with the star wheel pinion is it possible that you've go the barrels muddled up?

[gary17]

Yer that was what I thought but they are correct. 

Thanks

Gary

Ok, are the pivots on the star wheel pinion intact and properly seated in their jewels?

[gary17]

Yer

I will check to night just getting off ferry

hey

All seems fine as far as i can see. canon pinion may be a bit loose. if i could i would change it for a new one.

But as i say i don.t know what part to order.

need escape wheel and canon pinion.

So i shall scour the net but not holding out to much hope.

not a lot on ebay .

Cousins has all the parts for a 2612 but none for 2612.1 so a bit stuck dont want to buy the ones for the 2612 only to find they dont fit the 2612.1

thanks for all the suggestions though.

cheers

I took one apart a few days ago and took pictures. Do they still mesh (they shouldnt) when you place the bridge?
