Greetings,
Some expertise needed here, as I couldn’t find the right matches googling. Perhaps some straps were for Chronostops, but not sure.
What are we looking at here? Are these 1960’s, -70’s, -80’ straps and bracelets?
What models would these have been for?
And of course, what would a fair price estimation be for these?

I’d guess the straps are for chronostops.

If you show the insides of the clasps they should have reference numbers which will help identification

Thanks. Yes, that’s what I thought. I don’t have these. Yet. But one of the bracelets seem to be for Constellation.
