hi guys i'm braking my head and buying 2nd time wrong main spring . can somebody help with rado 2797 309 can't find correct as far as i understood it should be eta 2783  and should be GR4006X but it does not fit. can somebody help to find correct?

Here it says the mainspring is 1.45 x 10.5 x 0.12 x 368mm. Which is  quite a bit shorter than the the GR4006X which is 400mm long

Cousins don't have an exact match but I would think the GR39981X or the GR3956X would be a better comprimise

What do you mean by it doesn't fit and photos would help.

ETA 2783 from Cousins so the question becomes are you sure it's a 2783?

Just looked at the Ranfft link provided by @ColinC and it shows the Rado 2797 309 as a 2773 which is the same GR4006X anyway.

No idea if Ranfft has it right... but there are 2 different mainsprings listed on the ETA2773 page - the same shorter one as was listed on the Radio 2797 309 page and the one that matches the GR4006X.

The 32mm difference in length shouldn't cause a problem with the barrel size.

The OP still hasn't explained how it does not fit. Is the spring too wide, or arbor too loose?

yes arbor doe not even hook to main spring really loose.

It looks there's no this watch for sale 

None now but that's why I said 'sold listings'.

There's also a lot of similar watches which should give you an idea of price.

    • Hi All, I’m having a hard time finding a balance assembly or even a working donor movement for a Gruen 330.  Any leads appreciated.   Gruen doesn’t stamp the caliber number of the movement but lust in the case back.   
    • Why do you think this is Fontainemelon ?  The balance staff you will need to source separately.  But first it's important to accurately identify what you have there. Research Ebauches Sa, see who was in group, to find the brand that made this movement. 
    • Hi Watchrepairtalk, I have some questions about part sourcing I was hoping someone here might be able to help with. I'm working on an FHF 180 movement with a broken balance staff, broken regulator pins, and damaged cap jewels (both top and bottom). Some Googling says that this is similar to other FHF calibers like 150s, 160s, 180s and so on but I can't figure out what the functional difference is between these movements.  Is there any reason I wouldn't be able to acquire a donor FHF 150 or similar (with no shock protection) and use parts from that or would it be smarter to source replacements individually? Also are there any sources someone could recommend to get bulk cap jewels like this? Thank you for the help!
    • Hello and welcome to the WRT forum.
    • interesting video nice to see the machine what it can do now I wonder what it costs and I'm sure it's not in my budget. Plus the video brought up questions but the website below answers the questions? What was bothering me was the size of his machine 4 mm because I thought it was bigger than that? But then it occurred to me that maybe they had variations it looks like four, seven and 10. With the seven and 10 being the best because way more tool positions in way more rotating tools. Although I bet you all the rotating tools are probably separate cost https://www.tornos.com/en/content/swissnano   Then as we been talking about Sherline. Just so that everyone's aware of this they have another division their industrial division where you can buy bits and pieces. I have a link below that shows that just in case you don't want to have the entire machine you just need bits and pieces. https://www.sherline.com/product-category/industrial-products-division/   Let's see what we can do with the concept I explained up above and bits and pieces. For one thing you can make a really tiny gear very tiny like perhaps you're going to make a watch. Then another version the center part is not separate it is all machined from one piece. Then fills gear cutting machines have gone through multiple of evolutions. A lot of it based on what he wanted to make like he was going to make a watch unfortunately eyesight issues have prevented that. Another reason why you should start projects like this much sooner when your eyesight is really good or perhaps start on watches first and then move the clocks then local we have from the industrial division? Looks like two separate motors and heads. Then it's hard to see but this entire thing is built on top of a much larger milling machine as a larger milling machine gave a very solid platform to build everything.   Then like everything else that had multiple generations are versions the indexing went through of course variations like above is one version and the one below was the last version. Now the version below I mentioned that previously and somewhere in the beginning to discussion and somebody else had one in their picture. As it is a really nice precision indexing. Then I wasn't sure if I had a the watch photos here is his unfinished watch. No he wasn't going to make a simple watch like none of his clocks were simply either what would be the challenge and that.
