Re: "Most mechanical movements only need to be disassembled and..."
ah! I try to stick with newish calibers. I imagine really old watches cost an arm and a leg. I like calibers that are simple and robust. The most complicated caliber I own is a SL4510 that I salvaged from a second hand fake Daytona with stucked reset. I've not had the opportunity to play with a real 4130, But the 4510 has rhodium plating and is otherwise well finished. I've been trying to find a good case for it without the Rolex logo and preferably doesn't look like a Daytona, it's been a pain. After that, my next step is to find a real 4130 balance wheel assembly as the old one has a large positional error, but I think this part costs many time what I paid for the watch!

The caliber is currently +5spd with a full wind dial up. But at 50% wind, it goes to +35spd! could this be the hair spring or is the mainspring also badly made?
@decant Not really. Most of my 1800s watches only cost $100-$300. I've gotten as inexpensive as $60 if they needed quite some works.
Most mechanical movements only need to be disassembled and cleaned once every 3 to 5 years. Yes you need a few consumables such as o-rings and few micrograms of lubricants of different grades. But a well serviced movement can last few decades. If you pick a mass produced movements, replacement part are relatively easy and cheap to source. The Swiss ETA2824 movement for example has been in production since circa 1974! Can you imagine such a long product life cycle in the world of electronics?...
