Movment Model

[LiamB]

Does anyone know what this Russian watch movment is? I beloved it is a poljot however I don't know what is the model. I want to know so that I can order a new mainspring. Thanks

variant of pobeda movement with central second hand as opposed to subdial,made by several manufacturers.  I believe it was called the sporting model.do an search on etsy. russian watch movement, lowest price first .you will see a lot of these used for very little money. of course they are parts only, but it sounds like parts are what you need

Think it's a Zim 2608 or 2609. You could probably buy a lot for next to nothing on ebay.

It must be a sim 2608, 

Does anyone know the mainspring dimensions?

You may struggle to find the dimensions in a catalogue.

I would be inclined to measure the old one as best you can and then measure the barrel and follow this guidance (reverse engineering calculator) to work out the optimum.

If both answers are the same you should be good to order the nearest available. If they are different, you have a choice to make!

Unknown....but I would guess that for the sake of economy the Russians kept it the same as the pobeda.order a few used ones.I would be surprised if you didn't find everything you need.

I ordered a mainspring, I'll keep you posted if it fits.
