I'll need to check a recent example. But I suspect yes.

I saw a post-2021 5711/111P recently, and it used the old clasp. It and the 5712 probably use the same bracelet and clasp architecture.

2022 as far as I can tell.

That's not to say that all the current Nautilus models got the clasp in 2022, but the 2022 novelties 5811 and 5990/1A-011 definitely had it from inception. Best, Tim
