Just to add to the mystery I was thinking about mainspring winders sets like specialized ones specific for various calipers. It also gives us a clue that there definitely Different if they are two separate winders.

SO i guess that the 6497-2 then. Is that right?

Yes that's what you need to do.

Then of course the problem is purchasing the right mainspring because a lot of the sellers seem to think that they're all identical and they lump them all together and they're not obviously.

great. Looks like gleave and co do the mainspring for this for 15£. Ill give them a ring on tuesday and check the arbor diameter for this, then hopfeully get the thing back running. Id assumed the most complicated part would reassembly not finding the right spring!!

thanks all.

so sadly im no further forward. Gleave and co politely told me that im stuffed with a chinese movement, would entertain any measurements of the arbor or barrel and tough luck.  

Anyone got any ideas. Gleave also said that i couldnt even add an eta mainspring and barrel to the movement as it wouldnt work.

As many probably have practiced on these movements id greatly appreciate further assistance!!!

 Replacement Watch Movement Clockwork Mainspring For ETA 6497-1/6497 Mechanical Swiss Watch Movement Repair Tool parts

Would this help?

But for that price, another £10 would get you a whole movement. That would give you spares for anything else that might break or go missing.

Thanks Hector, this is what im now thinking might be the best option, plenty of spares too.

Im frustrated that i cant get info on internal diameter of springs etc, as it means replacing parts like this is basically impossible or hugely expensive in terms of trial and error. 

 i wonder if i can find a used original eta on ebay so that i can actually buy individual parts with some confidence.

      This is not rare at all, the dial code and case code don't usually match.

      Interesting issue that I just noticed: this Seiko 5actus Watch from 1977 has a calibre listing on the dial of 7019-8030R but on the case back it says 7019-8010!! Like a mis-printed coin, is this watch therefore worth a lot of money for its rarity?? 🤪😲🤔🤪

      I wish that was the case. The Aegler movements used in the early days by Wilsdorf & Davis (for brands like Rolex and Rolco) came in several sizes and without designated calibre numbers that survive.  They become a bit easier to identify during the 1920s. Below is an Aegler-Rebberg, 25.74mm in diameter. It’s from a woman’s Rolex wristwatch. Stamped Rebberg and 500 on the dial plate (but it isn’t a Rebberg 500, it’s the wrong size).  I’d be interested if anyone can identify the movement.  It is based off the Aegler Nr.1, circa 1903, but they based many many calibres of different sizes on it. The closest I have to a positive ID is the  ‘Rolex Nr.50’ circa 1917, but no dial side images or movement sizes are available in the references. There are identical looking movements in many sizes.  The 25.74mm of this movement is a particularly strange size for the era, it equates to 11.41 lignes.      Best Regards, Mark

      FHF70 balance jewels settings

      By GuyMontag · Posted

      It looks like this movement comes with a number of different shock settings. Emmywatch shows that it comes in versions with no shock settings, 'Incabloc', 'shock resist', and 'Supershock'. Perhaps the different settings position the impulse jewel/roller table in a non-ideal position relative to the pallet fork/guard pin. Are you able to check under high magnification if the pallet fork and roller table are able to operate without any interference? Just for fun I took a look and I have one FHF 70 in my collection, a West End Secundus with a non-shock protected FHF70. I had a note with the watch that said, "Movement is stamped 'FHF 70', but the FHF70 looks to have sub-seconds instead of center seconds movement (??)" but that a google search turned up both types for this movement. EDIT: I just took a look in my parts drawer and I have a few of these movements, both in center seconds and sweep seconds, but they all are non-shock protected.
