I saw someone comment on YT video at some point that alluded to this being possible.

So stopped by my Omega AD this past weekend to have a look, take some measurements and actually try this out.

Of course I'm interested because the '57 clasp has push button quick adjust functionality.

And turns out - it will work! Slightly larger clasp but otherwise looks exactly like the 321 clasp. They're currently trying to find the part number and will then order. Swatch group had issues with their ordering system for the last few weeks but sounds like things have come back online recently.

If anyone else is interested, I'll circle back with the part number.

To be clear, this isn't a half measure like some were doing with the 3861 and Chronoscope clasp. It's a direct swap and the only caveat is the '57 clasp is slightly larger.
