Rolex 1500 Questions

[Allen24]

I have a Rolex Perpetual Oyster Date Model 1500, vintage 1974, movement 1570. To remove the movement from the case on most 1500s, one must release the crown by gently pressing in on the adjacent clutch pin with a fine pointed tool. My movement has no such button. I saw a video, but the critical action was obscured in the video by the author’s finger cots. I believe the author of that video had to unscrew one (or more?) adjacent screws.
Anyone out there who can help?

The 15xx have a screwed pull-out piece, not one that you press.

Buttons are new-age. As Bas mentioned, the older movements have a lock-screw, You only need to turn the lock screw a quarter turn of so, you don't really want to take it all the way out.

Thanks to Bas & Larry for their helpful answer. It would also help greatly if anyone had a photo or video of that or similar resources describing movement removal. Also, a recommendation for online watchmaking course(s) would be helpful. I’m aware of the online Naked Watchmaker course for $600. Basically, I’m a retired hobbyist with a long history of tool use, and various tech skills.
