The strap transforms and add great comfort to the Tsuyosa line. I would give this 5 stars if it had a second keeper. I’m a 18cm wrist and use the 4th to last hole on the strap. This leaves over an inch beyond the keeper just dangling which gets caught on things. A second loose keeper would help keep the excess strap down. That would lend to a cleaner look also. I’ve even tried reversing the setup so the excess is on the inside, towards the body.
