Poljot Russian Soviet Chronograph Watch | Full Service & Movement RestorationJan 14, 2022
Here we have a very nice vintage Soviet
watchwith a caliber 3133
movement. Now I'm not entirely sure how to date these
watches, but my guess is that this model was sold in the late 1990s, although the company had been producing these
movements since the early 1990s. from 1970. when they bought some equipment and tools from a Swiss manufacturer called valjew velgu, they were producing a very successful
chronographmodule, the 7733 or 7734 with their calendar from the 1960s, but when they started pushing the successor, the valjoux 7750 , which is still sold in watches today, a company in Moscow took the opportunity to buy the redundant equipment and used this equipment to produce this caliber 3133 and for all intents and purposes they did a good job so here we are. small cracked watch with a dual 23 chronograph movement the chronograph can record up to 30 minutes with a start stop and reset function as well as a 31 day calendar now a show at its age there are many small scratches around the case which BTW it is chrome rather than stainless steel and this means the case is not easily refinishable or refinishable but the scratches add to its charm and I would consider them a feature, in any case polishing this watch would definitely give as result in the base metal being exposed which would completely ruin it, the movement itself is running but it stops periodically and the chronograph won't run for any length of time before it causes the watch to stop so today I'm going to take apart the movement in pieces to find out why and I'll start by removing the back and then removing the movement from the case so here is the movement as s e mentioned it's a polio caliber 3133 and this is a cam operated chronograph rather than the column or column wheel type found on the seagull st 19 chronograph that i featured several videos ago there's a link in the description but as You can see, it looks clean.
Not enough rust or corrosion visible and it seems to have stood the test of time quite well. Now anyone familiar with the original value 7733 or 7734 movements will be impressed with the similarities shown here. The original values were produced in several different grades and finishes and you would find them in higher end watches like breitlings and this movement while not a high quality finish actually appears to be well built unfortunately I have not posted a video with the valjews 7733, but if one comes into my possession. I'll post a comparison video but for now let's get on with breaking this one down now in my previous video I reviewed this chronograph remover and found it very fiddly to use now as I've practiced with it and find it very useful but I intend to do a stand to make it more stable.

I'll make a video showing it in more detail, but the idea is that the tool will allow you to remove the hands from a chronograph without touching the di. al y in that sense it does a good job but i found the off center second hand has come loose from its collar at some point its quite loose the hand comes off its collar which stays on the 4th wheel pivot , I will remove it. that later and then try to secure the necklace back on the original hand but for now i'll go ahead and remove the rest of the hands and the dial now i know this watch stops periodically but it's running now so let's take a quick look at the time grapher performance and despite the fact that it's showing a gain of 100 seconds or so per day the reading actually looks pretty clean so calendar jobs are secured with this cover plate that's held by three screws and now I can remove the calendar components and now the pinion can be removed from the cannon, so by turning the movement I can now remove the balance assembly.
Notice there are a couple of shims under the balance now, it's pretty typical to find one or two of these stuck on Soviet watches, even some of the second movements and the like, but now I'll start dismantling the components of the kronecker and start with remove the springs that are causing tension and now the ratchet and click mechanisms are exposed. I can remove any energy left in the mainspring now the spring is quite sticky with old oil so maybe that's why the chronograph can't run for an extended period of time, actually it's more likely that this fiber is causing the detention. the mainspring i can go ahead and remove the paddles and the gear train and the mainspring cylinder and finally i can get the wax components well removed without a key and that's the movement stripped now it's ready to clean now clean the movement parts on the cleaning machine -camera I won't show that process here it's just 30 minutes or so of a basket spinning in various liquids but if you're interested I have a video on the channel that goes into the process in more detail now with all the parts clean I'll start to put the movement back together and well I'll start with the mainspring barrel and now I can put the wheelset back on and with that done I can put the crown together and the click works for you and now I can install the spring wheel ratchet.
I fixed it here a bit. That is actually the screw for the chronograph chamber. Now I don't realize this until I have
fully assembled the chronograph movement. So I had to go back down to this point again and correct my mistake, it's all a lot of fun, but now I start to assemble the chronograph mechanism and I'll start with the spring for the operation and return levers now, before I continue with the installation of the chronograph. chronograph, it is useful. to assemble the keyless works do it like this and now i move on to installing the chronograph wheel and minute register wheel mm-hmm so it was at this point i realized i used the cam screw to secure the timing wheel ratchet.
I had to reverse a lot of the work I had done so far. I won't bore you with that, but by the magic of video editing, here's the screw in its rightful place, so now, with all the chronograph components assembled, I can install the paddles. and trying to get this watch working again and i don't forget those two wedges and now i can reset the calendar it works now after some tweaking i managed to get a respectable reading on the time graph so now i can reset the dial and hands remember the broken second hand. I'll press to get the hand into its collar and it seems tight enough now.
One thing to note here with this move is that these stems should really be removed while in the headset position. Failing to do this will result in the return bar or yoke being dislodged from the slipper clutch and this will only be resolved by removing the dial hands and calendar work and when you replace the stem do not press it until you are depressing the adjusting lever otherwise otherwise the same issue will now occur off camera, i cleaned the case and bracelet in the ultrasonic cleaner but as mentioned these scratches will remain part of the feature set of this watch due to the chrome plating but despite that, now it's a functional and reliable little chronograph maybe the only thing now needs a nice leather strap but let me know what you think in the comments below but that's it for this video thanks for watching and if you're not subscribed yet feel free free to do it now and if you click the bell icon you will be informed when i post new content if you want to learn more about the lubricants used here i have produced a free table of recommended oils and it is available via the link in the description and thanks to all my patrons who make this possible content take care and see you next time bye
