Maybe that's their way of protesting for remaining in the box.
I like the clean inside with no mechanics visible.
But i'm fighting like crazy just to close the caseback !

Now there's something you don't see every day - a red display digital BULETRONIC. The only bulgarian watch brand, produced for a short period of time at the end of the 70s, beginning of the 80s. About 10 different models were made, this one is M10 CH, whatever that means.
I've been looking for one for nostalgic reasons, so today I was given a non working one, to see if it can be saved.
Heavily oxidated, but with the right materials magic can happen. Enjoy!

I knew I had seen that trimmer somewhere before, it is the same as on a Ruhla Calibre 28. The trimmers were imports from Japan.

I just never bothered taking them out the box to set them on summer time :)
Buletronic was produced in the Pravec semiconductors factory, which was producing personal computers (IBM tech) and electronics for the soviet space program. Bulgaria was the only non soviet state to have more than one cosmonaut in space thIntercosmos, but judging by the accuracy of these two, there's no wonder no buletronic was ever worn in space.
Bulgaria was never the cutting edge of watch production, so there must have been some help from friendly experienced watch makers like Ruhla and the russian watch factories. Pravec probably produced some elements for their production, colaboration was in the essense of socialist economy. It's just watches wasn't their thing, they had no tradition in it, but they were probably forced to produce a bulgarian watch, cause it was a question of prestige, and someone had to do it.
I'm happy they did, as these watches are fun, pretty good build quality and a cool collectable nostalgia. Maybe theres a setting to calibrate the thing, I don't know. Never was familiar with quartz tech.

That's interesting to learn. There must have been some reason to concentrate this sort of production there. Maybe there was a research institute locally or something? I would not be surprised that because Ruhla imported them from Japan for its own watch production, that Ruhla then sold them on to Bulgaria in the fraternal socialist economy.

You can regulate the quartz watch with the trimmer. a very gentle small turn of the screw one way or the other. But I would be cautious. Whitelion is the person to ask.

Not sure this deserves a before/after since it's only a new battery and a light cleaning (interrupted by a lack of sand paper). but Im glad to see it all shiny and working.
All functions are operational, including the light.
Thanks a lot Ivan for the tips and encouragement !!

Congrats on your new 40 year old watch! The stylish monochrome design and the stainless steel case have let this watch age really well. Also the 20mm. lugs allow for wider bracelets. It is a vintage watch that you can actually wear on every day basis.
I may try regulaing my, as Secondtime advised, and get them some more wrist time.
Enjoy the weekend!

On pictures, i had a small preference for the black version, but now that i have it on the wrist, i appreciate the sobriety of this monochrome design and you know i already had a weakness for eastern steel ;-)
I'll also give it a try on a black leather or a canvas for contrast...

Not a russian, but this one was in a lot of mostly russian broken watches.

Good chance to play with Seiko's 6139 chronograph. Couldn't miss that chance. Waited for some button springs from UK and hands set from Singapore, or whatever.

New hands turned out to be crap, constantly slipping on the pins, so I got tired of that and returned the original ones. My watchmaker friend gave it a try, trying to fix the seconds hand, but finally he gave up too and said he'll just put whatever he can. So now it has a 3133 chrono hand.
Replaced parts - mainspring barrel from a 6109, seconds hand from a 3133 and a set of button springs.
The final touch was the crystal polishing, which today I figured out how to do. It took 7 different grain water sandpapers and the 3 finest polishing pastes from the autopaints shop down the street. My first try at polishing glass, and I was pleasantly surprised from the result.

For a moment, I thought it was going to be a Ruhla! But alas no.

But nevertheless, a good job done on the Seiko. Seconds hand doesn't look out of place. Sometimes replacement hands are a poor fit even if they are original. The tolerances are so small just a slight variation in manufacture and they can be too loose or too tight.

Are you sure you haven't got a Ruhla in that batch of watches?

Thanks, my friend! At the beginning of my watch obsession I was buying off many broken watches from antique shops. One of the first was a Ruhla chronograph, black dial, golden subdial. I was nowhere near the knowledge and experience I have now, so I just kept it in a box. Later I met my Ruhla collecting friend (I've talked about his collection) and I gave him absolutely everything Ruhla related. Now maybe I would have kept the chrono, but then again, if it came to me once it will come to me again. I will get my chance to work and play with one soon enough. If I ask him he will probably sell me one of his, but where's the fun in that?

I got really bored today, so I stuck my hand in the spare parts (junk) bin and pulled out an unloved Vostok 119 and gave it some love :)

My self imposed rule was to only use the original parts that came with the watch, so the crystal need some love, the hands needed de-rusting and new lume (aged lume of course) and the dial needed a clean. The movement was a runner (although in need of a service) and it was regulated to -15/+25.

Nice, keeping it real.
What lume do you use and how do you apply it, if you don't mind me asking?
Thanks.

I use Anchor Luminous Paste, and add a tiny little powdered Brown watercolour to "age" the mix.

Excellent job, Mario, and on an excellent vintage barrel! You should get bored more often :)
I got bored today too, so I decided doing some cleaning and sorting of some old scrap. It had piled in a box over an year's time. I bought some lots of scrap watches for pocket change, only to use something particular, and threw the rest in a bag.
So today I took that out to check if something is useful and throw the rest in the bin. I got to this broken quartz watch and almost threw it away. Can you guess what bracelet it had on?

Well, yes, it was russian, it was steel, and someone had filed the end links to fit this watch narrow lugs. Some damage was done to the bracelet too, but I'll live with it.
I replaced the end links, did repairs on the locking part, and fitted it to a more appropriate watch. Wait for it, here it comes ...

I got so excited that I forgot to clean and polish it for the camera :)

That is quite the classic Russian bracelet too!
I have a few old Soviet ones and they are all "OK" at best...

Good to have for originality tho, even if not for daily wear.

Great job!
Thanks, John!
Yeah, for originality mostly, I guess. I have a good collection of Poljot, Vostok and Raketa bracelets (stainless steel), and I don't really wear them. However, I didn't have this particular OKEAH type bracelet, and finding it in the trash was really cool.
My most comfortable bands are actually a recent DIY invention of mine. I needed comfortable bands for my work watches, and I liked the idea of elastic bands the cosmonauts used over their space suits. Kinda like the french Marine Nationale type bands. I just needed a band that will allow me to quickly pull the watch up my arm, in case I have to get my hands durty or in the scratch zone.
The answer came from the most unlikely place. Please don't laugh at me - men's pants suspenders. Don't remember posting this, so there it is. Easily adjustable for the perfect fit, washable and breathing :)
Maybe I should patent this stuff :)
