I was trying to figure out how much they were, and found the BLS inflation calculator I've used for years seems to be broken, as it has for several days:

This is kind of disconcerting.

I'm guessing those watches were around $1300 in today's money based on a site that claims to get its figures from BLS.

That seems to be fairly close going by https://blog.crownandcaliber.com/rolex-submariner-watch-pric...

The price shot up when they started making them two-tone e.g. half steel half gold.
