You should look for a set. Case tube and crown. Like Nanug said, perhaps it will go right on. If not, you will need to tap the case. Also like Nanug said, get a new stem. Better have it and not need it, than to need it and not have it..
You should go with an asian 2836-2. It's 28,800 bph, and will fit in your case. You will also need to get a set of milgauss hands, as the ones on your watch will not fit the eta. You're looking at a total cost of around $125 if you do it yourself.
I like it. It's amazing that I had the same watch 20 years ago. It had a 390 movement, of which I'm pretty sure, 67 was the last year for that movement. I had the dial refinished to day rolex and installed a sapphire crystal. Kept it 5 years and sold it for $1150. I made $850. Should have left it alone and kept it for a little bit longer LOL
Amplitude is the distance in degrees that the balance wheel travels before it stops and starts the other direction. The average swiss movements come in at 310-320
That is a lesson we all learn, over and over again. I won't take any deposits on watches anymore. Never seems to end well. The thing is you're a trusting soul. This time it did not work out. I'm sure you will trust again, and that's ok. I'll bet your life is much better than his. Happier, more successful, and blessed everyday.
Well, rules are rules. I think you caught the mods on a bad day. But when in their house you play by their rules. I was banned after 2 weeks for my response to a warning I was given. I don't miss them at all. Welcome to the lifetime ban club from rwi.
Actually the 1.8 and the 2.0 are the diameter of the springbar. If you have a no holes case you want the flanged springbar, probably 1.8 if its a rep rolex
