I can't believe I'm writing a review for a watch strap but damn this is a nice watch strap!
Looks great on my vintage Vader Helmet.
The Bonetto Cinturini strap complements my Seiko "Bottle Cap" diver nicely. It's thick at 4mm, rugged, and sturdy. It's not easy to cut to size, but that characteristic increases my confidence in its craftsmanship. It's manly, like me.
Thicker than the 300 series, yet supple. Great eggshell texture on one side making it look matte. Vanilla scent not as strong and objectionable as the other bands. Very nice clasp.
Good quality and very comfortable. Don't be fooled by stamped clasp, it's solid and well made. But, for the price of this strap, it's worth buying just for the rubber should you choose to replace the clasp. It does have a fairly strong, but not unpleasant vanilla cake smell. It fades slightly after some time, but it's still pretty noticeable. Will likely buy more as my watch collection grows.
