santre22 Do you think it is possible to do this without any previous experience in servicing watches, just using your detailed instruction? Or will it end up with a spectacular failure and the need to buy a new watch?

No way! Buy a cheep one first and try. U will fail.

The "problem" it's all the "hardware" necessary for the service and of course: know-how and practice it's crucial for these kind of work.

Do not forget that you are looking to pictures that are amplified. ;-) About me, I'm not able to do it, it's needed a steady hand that I do not have (and to be fair, also don't have the know-how and practice).

This topic is the best tutorial that I ever saw about service in reps, so your local watchsmith with the prints, for sure that can handle the job. ;-)

I have a Breitling Navitimer GMT with a A7750. Thought I'd service it myself. I now have a replacement Navitimer GMT on the way. This one I will NOT service myself.... :D. I also have a custom annual calendar IWC Portugieser, which has to be shipped back to ZF in China because my local watch repair shop had a meltdown when they realised how complex it is, no way that you could service that if you don't have the practiced skills and a steady hand.

My own mental note: find a rep friendly repair shop that is willing to take a chance on the custom stuff, or stick to the Valjoux or ETA clones, or even Miyota/Seagull, if you want to keep things serviceable.

Yeah, I can picture myself in exactly same spot :D

Little to late for that second option, so as I said gonna translate this thread, print it out and make a journey through repair shops in the 'hood.

I was reading through the thread, but the size of the winding stem was not mentioned. There are two sizes of 7750 winding stems, the 0.9mm and the 1.2mm. Is it the 1.2 in the 8500 clone? Thanks!

Thanks for this, it is tremendously helpful. Did you service the mainsprings and reapply braking grease to the barrels?
