Wow! Did you swap out the balance & bridge - straight swap?

Forget that, obviously both as the gen has no regulator arm.

Luckily this is a captive spring so won't fly away when released! Good luck.

Deeply shocked & saddened to receive the news of the passing of Nanuq. 

My sincere condolences to all your family. A true gent has been lost.

You have a older 21,000 vph movement based on the Valjoux 7750. The newer ETA 7750 has a beat rate of 28,000vph this will explain the different tooth count.

This is the wheel you require (or similar)

Part number is Valjoux 705

Hand winding auto mainsprings...hell no! Especially on those tiny modern calibres!

Only mainsprings I hand wind are those that are not replaceable, easily. Other than that, new mainspring, pressed in.

I have on occasion came across new mainsprings that the retainer ID is larger than the diameter of the barrel it's going into. On these occasions, It has to come out of the retainer and be wound into a mainspring winder.

Mainspring winders are ridiculously expensive but I managed to get a decent set, without remortgaging the house.

As, said above make a note or take a picture before removing the old mainspring so you know what way it goes back in.

I dont want to say that I saw this coming, but I never liked him. He didnt feel neither helpful nor genuine. Always trying to sell old beat up [censored] as if it was something rare and the best thing since sliced bread.

Well well money; the root of all evil.


Any links to the threads where he sold rep parts?

Some of his sales threads made me cringe.

Yes you are right you don’t know me and I don’t know you either. 
I am just looking for suggestions..
thank you 

How did you come by such an extensive supply of restricted parts?

These cold be advertised on any public site, why choose a forum for replica watches over a forum for genuine watches and parts?

Currently repairing a ETA 2824-2 with extensive 'drop' damage. Parts required for repair, Hour Wheel, Centre Seconds Pinion, Mainplate Centre Post & Escape Wheel.

All purchased from my supplier with no drama.

As you were...

There are eBay sellers that sell decants of Moebius lubricants (and other brands) I went down this route with the Horotec Episurf-Neo (epilame treatment) got 5ml as 100ml would evaporate faster than I use it!

Handwinding mainsprings is never a good idea. New mainsprings will general just slip straight into the barrel from there retainer, just a little braking grease on the barrel is all that's required.

If a new mainspring is available, then use it. 10 bucks for a spring is worth it just for the peace of mind.

If a new mainspring is not available then a drop of D5 on a lint free rag and the spring pulled through. Invest in a set of Mainspring winders, the Chinese sets will suffice as long as you use them carefully and are not doing too many springs with them (the brass arbor hooks are their weak point)

Gone over most of what was said by @automatico good, sound advice.

Little dab of blue loctite should keep it in place😉

There's a fake plate glued on top of the regular screw. You will need to remove it to gain access to the regular screw.

This is not an expensive watch by any means, but I've had my eye on this one:

Just seems like a cool and fun piece

I trained in Horology with the guy that puts those watches together and owns Mr Jones watches!

I think the 5500 case would work well with the MoChaCha dial which is 27.2mm. You could use a 2824-2 with or without the autowind assembly. 

I'm not familiar with the MoChaCha dials.

Could you point me in the right direction?

I have a 2824 auto in the case already so it would be just dial, hands & crystal I presume?

Cheers.

Like it!

Would a gen 5500 case (complete) be a suitable base to start a build?

Grand Seiko. Heritage Collection.

My 'ono' meter is strong with this one...

There are some guys on this forum that would kill for lume like that though!

"close" won't be good enough. It has to be exact. That movement is a AS 1677. 

Chances of a match...no idea! Remote i'd say.

The jewel is set in a brass setting so polishing it to size is not possible.

Communicate with this guy... http://www.obsoletewatchandclockparts.com/wristwatchmovementsFto.htm

Explain what you have and what you need, he may be able to help.

so you have the balance cap and shock spring attached, but no balance wheel jewel?. This will be difficult to find as it has to fit both in diameter and depth

Spot on, the balance jewel is missing. 

For your information, the movement you have is a FHF 76. Unfortunately, it appears to be an unusual variant as it has this tri-shock protection. Most, according to google and Ranfft ( http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&0&2uswk&FHF_76 ) have the common Incabloc shock protection. 

Unless someone else has a solution? You could take a chance on this... https://speedtimerkollektion.com/shop/product_info.php?cPath=32_222_100&products_id=19233 

It has the Incabloc protection. There is a 'chance' that the balance jewel will fit and you can then install your tri-shock end stone.

There is the possibility it will not fit and you may be able to use the entire mainplate, although it looks pretty shabby.

Anyway, you now know what your movement is & what is missing. 

Bezel don't look gen.

You sure you're not 'long screwing' that balance c*ck!?

Wouldn't be the first time someones put a long screw in a short hole....

2836-2 uses a Etachron regulator.

You need to study the correct method and use the correct tools, to do it properly.

Watch & learn...
