zenith part name


Recommended Posts

Hey

I am back working on this zenith 2542c. I have fitted a balance complete and all was well and i noticed date was not changing so i stripped down the calender side and i have come to this wheel with teeth missing. ( i am presuming this may be the problem)?. I cannot get a work sheet for this caliber so cannot look up the part name. Is it the date jumper? date jumper wheel? or what?

Part name and number would be nice.

pics below

cheers

Hey 

Yer that part HSL gave is for the wheel above (the empty wheel space. )The base cal is 2540.and the sheet he sent is for 2522 which is not in the 2542 c family. 

Just need name of the circled part. 

Cheers

You have the complete collection , just look forward in the sheets they go from 2522PC - 2562PC.
For movements this old there seldom are any step-by-step instructions look in the 2552PC sheet for the numbers.

hey

Sorry it might be the complete collection but still one missing. 2542c. I know ranfft says and movado say such a thing but there is not the piece i am showing in my pic. 

I have looked at the worksheets for 2522,2532,2542 etc with or without the p or pc and none of them look like this part.

I think its the date jumper but all date jumpers shown on the work sheets i have show this as a wheel but with out the slot in it..

HSL has given me all the worksheets he has and pointed me in the right direction which im gratefull for (thanks) but i cannot see the part in any of the literature

The interchangeability list for the jumper says it derives from the 2572pc and is number2575.

but i still cannot find a picture or a drawing of this part.

if you look at the wheel i have circled it consists of a wheel with a slot cut out of it.  on top of that secured by a screw is a collar with a pertrubing finger that fits into the slot in the wheel. none of these pieces are on any worksheet for cal2540 (ranfft call base) up to( 2572pc that interchangeability seems to say is a dirivative ???? of the base.)

surely we have someone in here who knows zeniths.

cheers

Hi again Gary ,
The parts for the calendar is the same for all of these Zenith movements regardless if it is a C or PC the main differences between them is that your model C is manual wind and the PC is Automatic.
The only one in the 25XX series you can’t take all calendar parts from is the 2522 since instead of a finger it has a small nob on the wheel changing the date instead of a finger.

Pictures and numbers usually are the same regardless of language but just to clarify what the parts names and positions are I add this picture for you.
We have the (2542) the double calendar setting wheel which is driven by the hour wheel. If you don’t have this you need to order this part too.
The double calendar wheel drives the (2615) date finger driving wheel, this is the part you have the three damaged teeth on. As you see there is a slot in this wheel and there are where the (2552) date finger goes.
What you have to investigate first is why those teeth on the date finger driving wheel is gone, usually when it looks like that one has mounted the date wheel wrong, it is jammed. If something doesn’t go easy one can’t just force the date change.
Next you have to see if you have the double calendar setting wheel. Otherwise, the date will not change.

Now I will go back to the BBQ and pop a beer or 20…

Hey guys been working on this watch a while now put it back together and noticed calendar not working. Seen some teeth were missing from a wheel and with help frompeeps on here (HSL) i managed to order thge correct wheel. After putting new wheel on and trying it there was still resistance and the wheel would not turn and so the calaendarf would not turn. I did not want to mess up the wheel so investigated a bit more. The part in the first pic (Boscule de d6clonchement de I'indicoteur
de quontidme) the hole should line up with the hole just beneath you can see in pic 3. In pic 4 the parts called (Ploque de mointien de boscule de
d6clonchement) goes on top the circled parts are circle 1 and 3 take screws and when i first saw it . it had a bit of metal going through the (Boscule de d6clonchement de I'indicoteur de quontidme)

and the part  (Ploque de mointien de boscule de d6clonchement

Now i know this is wrong but what should be there?

Sorry about the french but its the only thing i have.

cheers

    • Thanks, ManSkirtBrew.  I started looking for a setup like yours and ran across this.  It was about half the price of the JKA Feintaster (depending on what auction you were in), and it's a Bergeon.  I bought it because I thought the price was fair (eBay - Buy it now), and I'm a sucker for vintage tools. It also has a table, so it should be easy to use for measuring jewels. I wonder if the the contact points can be changed out. Bergeon seems to manufacture new tables and accessories for the contemporary dial version. What do you guys think of it? I'm sorry this post seems to have taken a detour. I'm new here so let me know if I should start a new topic.
    • This is a flying cutter, usual one. The cutter itself is shown in the pictures in the first message, it is made of broken tungsten carbide drill bit. I asure that all the angles of the cutter are as they should be. I have video - little older one - that I made when onse making the same kind of winding pinion for a Poljot 2200, which is even smaller than this one. It is not easy to see in the video, but the tool rest moves about 1mm towards the object in Y direction and then returns back untill cutter is rotating. Then the spindle is rotated one tooth ahead and everything repeated untill all teeth are cut.
    • After a bit further research could it possibly be an AS 970?
    • Latest project was a non-running ebay purchase with an FHF70 movement. I stripped and cleaned it, reassembled it, and got it running. So far so good, nothing damaged AFAIK.  I was oiling the top jewel on the balance (the one in the cock) which was a slightly unusual shock setting. I removed the spring (3 leaves) which was part of a chaton holding the cap jewel. This left the hole jewel behind which I retrieved with rodico and then lost it. I was taking it off the rodico, very gently as I thought, with tweezers, and then it just disappeared.  Fast forward a week, I got a donor movement, non-running, with the plan to just take the shock jewel that I’d lost. It was the same movement but had standard incabloc settings, and was steel rather than copper/brass.  I changed the cock and balance complete and it ran, not very well. I switched the lower jewel setting, cleaned and oiled both jewels and the replacement balance. Without the pallet fork the balance swings very nicely with a puff of air. With the fork in place, balance out, it flicks side to side nicely with power in the mainspring.  Put them together and it doesn’t run. The impulse jewel sits in the fork and it stops.      Any suggestions how I proceed? In case you didn’t follow that I have 2 FHF70 movements, nothing broken as far as I can tell, but mixing up the balance wheels and jewel settings results in a non runner. 
    • Oh and this almost perfect third wheel pivot and slightly set mainspring  Ah ok yes i see what you mean, good idea. I'll try that if i fluff this one up. The image isn't great quality but i like the idea though.
