Mig 21 Chronograph

[matabog]

Hello!

Could anyone help me with some more detailed information (service sheet, manual, etc) for a russian chronograph Molnija 81322? It was (and still is, from my knowledge) used in MIG 21 airplanes.

 

Two links that I've found:

Thank you,

Very nice Bogdan, that is beautiful! I wish I could help...I can only admire the movement and wish you can sort it successfully!

 

Cheers,

Hi Bogdan, what a coincidence, I am waiting for one coming from Russia just now. Like you I am trying to find out as much information as possible. I will forward any information to you if and when I come across any.

[matabog]

Thank you and be sure that I will also share everything I found.

Hope it helps!

Excellent Bogdan, there doesn't seem to be too much on the net about them. Here's another snippet http://m.imgur.com/UL8j9b3?r

It says Waltham aircraft clocks, but scroll down the page and you'll find information on an A4C-1 chronograph clock.

Hello!

So I made a 3d case in openScad and a friend of mine helped me print it.

 What do you think?

[bobm12]

I love it! How do you go about 3D printing of cases? I'd love to make one for a wrist watch (movement 2428)!

Cheers,

Bob

PS. The color is perfect!

[matabog]

3D printing is like a dream-come-true. You dream at something at night and then you print it. 

I have a friend who invested in a 3d printing machine, but he still makes small adjustments. This was his first big project - 32 hour job. At first attempt he had some trouble but at the second attempt it pretty much got the job done.

The case isn't perfect but it is ok for this particular project. It has some 0.2mm granularity (layer thickness), it's plastic, and I don't think It is appropriate for wrist watch cases - but I will give it a try at some point.

I'll let you know.

That looks the business Bogdan.  You've just got to fill the star with some red paint to make it look really .

Mine is still sitting in its original 1980's polystyrene packaging complete with original certificate.

[matabog]

Thank you Geo, but I don't want to make it too cheesy. It's got Mother Russia already written all-over it :D.

About your chronograph, didn't you have it serviced? Mine has the original seals on it (I guess) but I am itchy to open it myself - I think the parts are big and might be a good start on a column wheel chrono dismantle.

I've not serviced mine yet Bogdan, it is NOS with original seals.  It may be a lot bigger than a watch, but It's a complex mechanism built in two layers.  I would recommend learning on a cheap chronograph watch before servicing your clock.

@matabog Wow.......that is a great 3D print result. When I saw you & Geo talking about this chronograph, I was seriously considering buying one. But what when ready? Where to put it / build it in?? I think you found a fantastic solution and my compliments to you and your friend

While searching for the Mig 21, I stumbled over the Vostok watches. I was so impressed about all the technicalities / capabilities, that I bought yesterday my first Russian time piece; a new Vostok Amphibian "Radio Room"......I can't wait to have a look at the 31 jewel 2415 movement! Thanks to both of you for pointing me East !

@Geo  Actually it has three (3) layers: one "normal" watch with the train of wheels and barrels and escapement and... wait for it... and two independent column-wheel chronographs. It is quite awesome!

You are absolutely correct Bogdan, a bit of brain fade with my ageing grey matter.  I even had that link saved fir future reference.

[matabog]

Also, if you have a 3D printer, you could make your custom made movement holder (in this case for a 54mm/24 ligne Slava 5498 timer rattrapante 36000bph movement):

update. The planes are Herpa models

[szbalogh]

I want one on my desk!

[Geo]

Very nice Bogdan, have they been breeding?? 

[matabog]

:)) in the lonely hour....

no, I made different models for my colegues at work.

[Cad101]

I can honestly say they are quite spectacular a job very well done.

[matabog]

Thank you!

I'm green with envy but at least I know what my desk clock is going to look like.
