I thought I'd go ahead and try switching movements between my 2657 and my 2757 today. I watched all the videos I could find and the 2657 went great. I undid the case clamp and out it came. The 2757 on the other hand was still tight as a drum after stem and clamp removed. Can anyone please tell me what I missed?

I can’t help you with your question, but why on earth would you try to swap these date and non-date movements?
A few years of training and a lot of experience. Last time I tried to do something similar to what you said, I totally horked it up and had to pay for the full service, because it was coming apart anyways.
Ain't no point when a watchmaker who knows what she's doing can do it right in mere minutes and for a not-huge amount of money.
Reminds me of working as an electronics technician at the university where I eventually earned my degree. Computer science professor tried to "fix" his PC. Totally horked it up. (Yes, I like that phrase!) Generally wasn't a good idea.

If the process had included more than a caseback removal and 2 other screws I wouldn't have bothered. Watchmakers are few and far between here and those willing to even look at a bumper even fewer. I was quoted by one $95.00 to install a bracelet lock spring and screw in the retaining screw (using MY spring). If it had been even half that I'd not have batted a lash but $100 for 10 mins was a little steep for me as I work physically for a living.

I've gone into it in another post but the cliff notes is: I bought a 14k (case/bracelet) 2657 with a TERRIBLE redial and missing stem/crown. To replace the dial I sourced a nice original dial in a well loved 2757. I'm not a purist and want a nice looking watch to wear with a suit a few times a year. The movement switch was a quick "test fit" to see what they would look like t in the opposing cases. The plan is to keep all parts together so if passed on new owner can reverse the process. The 2627 removal was 1 case clamp and would have been a stem removal both of which are very easy. I was under the impression the 2757 was the same process.
I think I’m following now - all of your references to “2657” should actually be “2627”? That makes more sense, since they’re both date at 6 references.. vs 2657 which is a non date, sub second reference..
