I know I'm going against the grain here, but I like the contemporary buckle (don't know if it's really called that or not). I have a couple that are 22mm, but is there one in 24mm? Looking for a polished one.
I'm pretty sure I've seen "thumbnail" buckles like that in 24mm, before. Not that have the "Panerai" engraving on them, but just plain aftermarket buckles.
