I have been wearing flex bands on my watches whenever I could for most of my life.

This Twist-O-Flex "Romunda" is by far the most attractive flex band I have ever owned.  It fits my 7 1/2 inch wrist perfectly.  And, even better, it's an awesome match in size and color to my Casio Men's DB37H-1AV Multilingual Databank watch. I find it very comfortable to wear as well.

If I could be "In Love" with a flex band, this Twist-O-Flex "Romunda" would be the one.  Check out the picture of the band on my Casio DB37H-1AV watch that I posted here.
