Excellent watch supplied at a reasonable cost and great speed by FirstClassWatches. The Sieko Rotocall is a reissue of an 80's model which was used by many NASA astronauts on trips to the ISS. It's popularity among astronauts was due to it's clear display and ease of use in swapping between modes by use of a rotating bezel. Having had the watch for a couple of days I can see why this watch was an astronauts favorite, the rotating bezel is a joy to use and I find myself actually using modes that I would not have bothered with using if I had to fiddle with small buttons.
