I use a substance made by a company called Watchfix.com I got off of ebay, very rarely do I need to do two passes and is designed to work with a mop on a dremel keeping the speed moderate. Polywatch I have to have two or more goes to get stubborn scuffs out where this Watchfix stuff is pretty damned good.
Unless you have access to a chrome plater, you won't get the bezel back to original, they make that particular model still often seen on new 090's.
Watch movement is a common or garden 2414A. From Komandirskie.com the hands around 150 roubles, Movement 1999 roubles, crystals about same price as hands, you might have to mix and match between the Komandirskie arrows and a set of Amphibia hands for the second hand, its strange as my tank commander has the big straight second hand. Crown is a negligible amount and you would have to chat with them likely to get the correct crown.
You can of course pick up a working standard used Komandirskie for £15ish easily and if you aim for the "Made in CCCP" logo'd ones you would have the correct period movement. Your main hands will clean up nicely with a gentle brushing/fibreglass pen, reluming isn't too hard a job either. Painting the tennis ball second hand just use a red enamel modellers paint or an acrylic paint then relume same way as the main hands. I use a flattened slab of rodico for any hand cleaning or painting, be aware the minute hand has a crook and its quite easy to accidentally straighten them out.
What is the exclusive thing for your watch is it is a Zakas MO CCCP labelled one, people out in civvy street got the made in CCCP ones, only those with access to the exclusive Russian military outlets got the Zakas ones.
I can def recommend Komandirskie.com's crystals, I have used Meranom ones as well and just as good but Meranom don't do the "gilt ring" crystals which has a gold tension ring which looks super cool in a TiN case, the thing I had with Meranom's crystals is you have to fight the tension ring in a bit to get it to sit properly, Komandirskie.com's crystals the tension ring clicks in firmly to the base of the crystal.
