Certina was on the forefront of early ocean exploration, and was intimately involved with the Tektite Experiment of 1969.
Fun little read for those interested:

So, my little worn and pre-loved definitely has the battle scars of a watch that was truly purpose driven. It is likely the UFO model of 1968 with a tekitite/1000ph hour and minute hand set (they should be polished steel), but beggars can't be choosers.
Looking forward to receiving this later in the week. The fever has been full bore for a few years...
