I don't ordinarily consider buying a strap that is this expensive, list $90, on the net around $70, but I have to say that is is well worth the price, at least in my opinion!
I put it on my Hamilton Khaki chrono and it looks perfect! The Trieste is a composite leather/nylon/rubber strap with butterfly deployant clasp. It took me just a few moments to size it, unlike many other rubber 'cut to fit' deployant straps, and it is a perfect fit. The Hammy is 22mm, I know it also comes in 24mm for Panerai, and I think in 20mm as well.
, definitely my favorite strap!
