Works great for my old times indigo. For this particular watch,which has molded base bars & doesn't use spring bars, I kinetic kind of wish I'd picked a band without the extra set strap under the watch. My first NATO military strap. Great quality. A 20mm would work perfect for my Rolex Daytona. I can cut off the the unneeded strap and tuck it under the watch bar if I decide I don't like it. This watch locks in place on the strap. For watches with spring bars, the other set strap keeps the watch from sliding out of place.
