Two straps from AliExpress arrived today. First, the red fluorine strap from
this seller.
I bought this to go on my Mondaine Giant, but knew it was a gamble due to the very small lug clearance. Not surprisingly, it didn't fit. I tried it on the Nighthawk next but didn't like the look. Not expecting much, I tried it on the Visitor Duneshore Calligraph and liked it more than expected.

I also picked up a blue "fluorine" strap with deployant clasp from
this seller. I ran it through the "pet the cat" test (not a euphemism, just petting my cat as long as she would tolerate) and it did pick up some lint/cat hair. I'm guessing this is closer to silicone than fluorine because of the softness and lint attraction, but better than your typical cheap silicone band. Not sure I trust the clasp. Not bad, but not quite what I was expecting.
