Help On New Chrono - Valjoux 7733?

[GeorgeClarkson]

I bought recently this Gigandet Chrono with an advertised Landeron 248 movement - only to look way too much as a Valjoux 7733.... the classic case of wrong name made from the seller... Anyway, the thing is, as I have no experience on Valjoux movements as of yet, I am quite in the dark in recognizing the proper model type, especially based from the seller blurry pictures...

 

This is the picture that came with the auction:

 

 

An educated guess is that it is a Valjoux 7733, but I am not really sure, since the model no. is not clearly visible from the picture. I will receive this movement in a couple of days, so the mystery will solve itself quickly. The problem I have, is that I want to restore this movement and put it inside a nice case. But as I said, I have no clue where to start with. Could someone of you experts point to a manual I can download?

 

Any help will be appreciated.

This should help you George.

Thanks Geo. Can you confirm it is a Valjoux 7733 then? The dial, btw, says Gigandet... I coulnd't find much about Gigandet + Valjoux, honestly...

 

This is the dial looks:

 

 

I did find similar watches, but all have the 45 minute chronograph dial...

[Geo]

It certainly looks like a 7733 to me, and it does have Swiss on the dial. The Russian Poljot 3133 being a a copy is almost identical, but I don't think it is Russian.

[GeorgeClarkson]

And what about the 45 chronograph minute dial? Is this correct, since I found the russian "copy" you mentioned does have the 30 minute dial, like mine...

Here is a picture of the Landeron Caliber 248. It looks like your is a little different.

[GeorgeClarkson]

Yes, I know how a Landeron is, I habe one myself. I grabbed this one since I recognized it as a valjoux... But I was not sure of the model

[Geo]

Hi George, it would appear that the 7733 came with either 30 or 45 minute counters. Have a read of the specifications on the is page http://www.habring2.com/en/archive/chrono

[GeorgeClarkson]

Thanks, I'll have a look

Mm actually they don't specify which movement of the 7733 and 7734 has the 45 or 30 minute counter....

[Geo]

The basic movement is the same with the 7733 and 7734, it's just that that the 7734 has a date function so I would think it would be available as 30 or 45.

Thanks Geo, this makes me more confident that I didn't buy a fake

And finally, after more than two weeks, due to a strike by the post workers, I got my movement, and I do confirm it is a Valjoux 7733. The condition is great, it started ticking after I gave the crown some turns, but there are some issues with it, obviously...

 

1. I only have the chrono start pusher., The other pusher is missing
2. The dial is in very good condition, apart from being a bit crooked and presenting a large crack at 8:30, which led to some staining of the dial
3. The acrylic glass has some scratches, but nothing that can't be removed.
4. The hands are misaligned a bit, that that is no real problem...
5. I am missing now a proper case, but this I knew already :D

What I did notice, though, is that probably there is something wrong with the second pusher, apart the fact that it is missing, of course. There is only a small metallic spring where there should be a lever of some sorts... I am not acquainted with the Valjoux movement, so I need to study the manual first in order to be sure.

 

More to come...

[Geo]

That's good news that it's a 7733 and your pleased with your purchase. I'm looking forward to the next instalment already!

[GeorgeClarkson]

And now the search for a proper case starts... anyone got one that wants to sell?  :D

[GeorgeClarkson]

As I suspected, the Fly-Back Lever is missing, and it's screw broke inside te plate... I managed to take some pics, and to remove the screw. 

 

 

As you can see, part of the screw is still inside, on.ly the head broke. I was still able to remove it safely...

[GeorgeClarkson]

So now I will not only have to look for the fly-back lever, part 8180, but also for its screw, part 58180...

[Geo]

That's a shame George, if I come across one I'll let you know.

[Geo]

Here's one, but without the screw.

[GeorgeClarkson]

Hi Geo, thanks for the link, I had found it too. Two problems with it: it is in USA, which means high shipping costs and customs... plus the price: 45$!!!!

[GeorgeClarkson]

Am I wrong, or I read somewhere that the Valjoux is the same as the Venus? If so, is ther eany chance I can take an equivalent Venus movement or part for less?

[Geo]

I don't think so George, but I may be wrong. The Poljot 3133 is virtually the same, but not identical, although the part you require may be the same. The problem is Poljot 3133 parts are very hard to come by.

[GeorgeClarkson]

I do not know if this shop is trustworthy, but I found the lever at half the price... Here's the link, for those who need it also:

[Geo]

That's a good find George, I've filed that one for future use. Can they supply the screw that you require?

[GeorgeClarkson]

Hi Geo,

 

Yes it is  indeed a good find, and I already placed the order and made the payment, but the shop only reopens on the 2nd of August. The shop looks weird, though, there are a lot of errors and the invoice I received is almost unreadable. Wish me luck!
