Poljot 3133 chronograph

Recommended Posts

I finally took the plunge, buying what looked like a nice example (listed as needing a service due to the hands stopping)

P1060276_zpslpjatcsi.jpg

P1060280_zpsdsotcmfv.jpg

 

however, on stripping it down

P1060359_zpso9opa9je.jpg

 

I find that I need a few parts

P1060358_zpszic1txms.jpg

P1060356_zpsbtuyzflw.jpg

 

and a missing minute recording jumper (finger spring).

If anyone has a either just these parts, or a donor movement that they'd like to let go, please PM me.

I'd love to get this fully working.

It might be your lucky day. I'm away working away right now but will be home later in the week. I've almost definitely got all the bits you need.

Should be something in my 3133 junk collection:

The good old 3133. One of the most understated / underrated movements ever?

I love them.

So, today I received a donor movement which gave me these three needed parts

P1060634_zpsrl8ztpsm.jpg

 

so, knowing that I would be able to complete the movement rebuild I set about cleaning every part of the movement.

I do this by hand, one part at a time. Including each screw!!

The part gets immersed in essence of renata - this dissolve any oil, grease etc. but is non corrosive. While in the renata I use sharpened cocktail sticks and special cotton buds to dislodge any debris that won't fall off.

Once all the parts are done, I think clean each part under the microscope on rodico. The rodico picks of any debris still left. At this point I also inspect the part for damage or wear.

The gear train parts then get another bath in clean renata prior to assembly.

P1060636_zpsmnfszpop.jpg

P1060637_zpstlmgwpih.jpg

P1060638_zpsikbvbu9h.jpg

 

this is what came off from the initial bath (oil,grease and metal filings)

P1060639_zpsgxpqo1u2.jpg

 

the mainplate, bridges and other larger parts (including the balance assembly) also get cleaned

P1060635_zpsjghlhycu.jpg

P1060640_zpsthtp2fmw.jpg

 

here's everything after the first pass

P1060641_zpsuhmprceb.jpg

P1060642_zpsa05ao0jw.jpg

P1060643_zpsxss5apci.jpg

 

all looking very good and no further problems found.

With part 1 of the clean done I set about the final clean before assembly.

I start with the mainplate, making sure that every jewel is spotless, and has been cleaned with a sliver of cocktail stick (ensuring that the fibres that break off are removed)

This has a removable shock setting for the balance wheel (similar to the Diashock assembly found in SEIKO watches)

P1060644_zpshntgjuat.jpg

 

I carefully unhinged the two sides of the clip (not having done one of these before I wasn't sure quite how it worked)

This allowed me to remove the clip, the cap jewel and the frame

P1060645_zps4yikjiur.jpg

 

I then cleaned the frame and cap jewel

P1060648_zpsjpcp46i6.jpg

 

before oiling the cap jewel

P1060649_zpspx6pah0r.jpg

 

and putting it back on the frame

P1060650_zpswph3kn6l.jpg

 

then I very carefully re-fitted it

P1060656_zpsmuperttv.jpg

P1060657_zpsfao0x7p8.jpg

P1060659_zpsjgswhiau.jpg

 

so now I have the mainplate clean and ready to go

P1060661_zpsf9aqu8iy.jpg

 

usually at this point I will service the mainspring / barrel. However, not have done one of these before I decided to just clean it externally. I might re-visit this in the future.

As I assemble the movement, each part gets a second clean before fitting. 

Being very unfamiliar with this movement (and rather nervous) I referred to the pictures I'd taken at each stage of the stripdown to guide me.

I very carefully oiled the inner jewel on this assembly.

P1060662_zpsnifwhzet.jpg

P1060665_zpsz6d5n36a.jpg

 

before fitting it


P1060671_zpsfngwfcsd.jpg

 

In the above picture I've also fitted the train wheel bridge that holds the jewel that third wheel fits in

P1060667_zpsxsoiynfy.jpg

P1060672_zpsnkvxkcjp.jpg

 

then I oil the bush in the mainplate that will take the mainspring arbor.  I also oil the centre wheel jewel

P1060675_zpsoko1la4t.jpg

 

then I clean and fit the centre wheel

P1060673_zpsr3yitzc1.jpg

P1060678_zpsbmdquein.jpg

 

then the barrel bridge goes on

P1060679_zpswybmvyse.jpg

 

and I check that the train gear runs freely.

Then I fit the click spring for the ratchet wheel (being very mindful it doesn't ping off)

P1060680_zpsunnzal7z.jpg

 

then I quickly fit the ratchet wheel (holding that spring safe)

P1060681_zpsrdhxhftt.jpg

 

phew!!

Next I decide to fit the keyless works so I can get some power to the mainspring. Time for one of the new parts (the winding pinion) to be fitted

P1060682_zpsaxvogt5b.jpg

P1060683_zpsvpth2c7f.jpg

 

then I oil the hole that the setting lever fits into

P1060684_zps5ad4grjb.jpg

 

and fitted

P1060685_zpstzd5lzw5.jpg

P1060686_zpsp5luzimr.jpg

P1060687_zpsxovigzpm.jpg

P1060688_zpsp13lcdxi.jpg

P1060690_zps1xrqo29h.jpg

 

then another pesky (but well behaved) spring

P1060691_zps6lx4m0ea.jpg

 

and after fitting the setting lever spring

P1060693_zpsg5todnrr.jpg

 

the keyless works are complete. And we're getting there.

The movement gets flipped back over

P1060695_zps4creef3p.jpg

 

to fit the crown wheel assembley

P1060696_zpsexi5xx53.jpg

P1060697_zpsdg8ycfjt.jpg

P1060698_zpsw4kzf1ft.jpg

 

then I fit the escape wheel - to do this I had to undo the screw that was holding the train wheel bridge and very carefully locate the escape wheel pinions.

P1060700_zps5c63aalu.jpg

 

in hindsight this should have been fitted first!!

Next I clean and oil the pallet forks

P1060702_zpsvqfsq3ec.jpg

P1060703_zpsnugvbc8e.jpg

 

and fit them

P1060705_zpsdft1vukt.jpg

 

now onto the last assembly needed to get this movement running - the balance

P1060706_zpsbwe2wny4.jpg

P1060707_zpsn40qzsne.jpg

P1060711_zpszf1dbqua.jpg

 

perfect.

The balance cock had two shims under it

P1060708_zpsuy5mceds.jpg

 

I started off by placing these before placing the balance cock

P1060710_zps7sdaovbr.jpg

 

but soon realised it was too fiddly, so first placed the balance cock, then slid the shims in place

P1060712_zpso3vllc2y.jpg

P1060716_zpsfwgzyfyq.jpg

 

Then gave the mainspring a full wind (which takes quite a lot of turns of the crown), popped it on the timegrapher

P1060717_zpskysrkmnt.jpg

P1060718_zpsfg1ien1i.jpg

 

OK, that's a very healthy amplitude. After regulating it I got to this

P1060722_zpslrdgrgsg.jpg

P1060721_zpsatloghtn.jpg

 

woo hoo.

I thought this movement looked good.

Updates to follow when I complete the dial side and chrono re-build.

I made more progress today - Christmas Eve is made for watch tinkering.

I normally complete the dial side last, but on this movement I figured I'd get the easy part out of the way.

First part to be fitted was the cannon pinion

P1060723_zpsnyyz0pqq.jpg

 

I really like this movement - I feel like I'm assembling a tank.

P1060724_zps0jepfbr4.jpg

 

I should really have fitted the cannon pinion before the minute wheel as there is a high risk of damage if the cannon pinion is pushed down out of alignment with the teeth of the minute wheel. I was very careful.

Then it was the date jumper, first fitting the two brass washers

P1060726_zpstzh74xcs.jpg

P1060727_zpsqhppmscl.jpg

 

and then the date jumper spring, the hour wheel (with all of its teeth!!) and the date indicator driving wheels (one small, one big)

P1060733_zpseaokonab.jpg

 

then the date wheel

P1060735_zps52knlxw2.jpg

 

and then the date indicator guard (made of 1/4" steel plate)

P1060736_zpsaul0mpus.jpg

P1060738_zpsifevcsyo.jpg

 

and finally the dial rest plate

P1060769_zps7iouhyyz.jpg

 

and that completed the dial side. Now onto the chrono complication ........

I must admit that I was quite nervous about the chrono complication on this movement. There are a lot of parts and quite a few springs.

I started with the first spring

P1060745_zpspxoxla1n.jpg

 

which puts tension on the coupling clutch

P1060744_zpsqvndef6i.jpg

P1060743_zpsqhw0snqp.jpg

 

which got a final clean and oil before fitting

P1060748_zpsvx0pvl2b.jpg

 

next I cleaned and fitted the minute recording wheel

P1060749_zpsnwrybdia.jpg

 

then the tiny brass friction spring for the chronograph runner (yep, that just runs off the tongue)

P1060750_zpst9tgqijs.jpg

 

and the seconds recording wheel and minute recording jumper

P1060751_zps2vivuhog.jpg

 

and then the chronograph bridge

P1060753_zpsrdau9pct.jpg

 

at this point I was feeling rather proud of myself. But you know what they say ........

From this point things got a 'little' more complicated.

First to get fitted was the plate for the chronograph complication (very aptly named)

P1060757_zpsbpr9awki.jpg

 

Then I cleaned and oiled the sliding gear

P1060754_zpsuhorgbrg.jpg

P1060755_zpseqhgkici.jpg

 

this is held in place by a left handed screw, and placed under tension by another sping

P1060760_zps6dox8ebj.jpg

 

The next part, the hammer cam jumper went on easily

P1060762_zpsn0tchiyf.jpg

 

Next part fitted was the fly back lever

P1060765_zpsilrg6odu.jpg

 

I was starting to think that maybe I'd worried unnecessarily .....

But getting the operating lever spring in place was when things took a turn for the not so positive.

P1060766_zpsrkikn4ew.jpg
