Bonetto is top of the line as far as rubber straps go. I have several Bonettos in different styles/sizes. I had to return this one though because it was too thick to fit the fixed bars on my CWC watch.
Bonetto Cinturini bands are the best rubber straps around. Won't irritate your skin like some other cheap rubber, it's pliable even in the cold and it smells great but not overpowering.
This strap really lived up to my expectations. The look is modern, but it still keeps the military tradition of NATO/RAF-straps alive. Great look and very confortable, just don't wear it to tight (unless you want the clasp to fret into your wrist).
It feels very solid and the smell is superb!
The feel on the skin is really smooth, I hope it will last some time!
I couldn't find a plain black Marathon single piece vulcanized rubber strap on Amazon, so I bought this one. It does indeed smell like vanilla and it's comfortable. I use this strap on my Marathon GSAR.
