In 1969, Omega released the 200m range. The 300m was already established, as was the 600m, but there was a market for a more affordable tool watch aimed at amateur diving enthusiasts.

The reference 166.091 was produced with a Pilot Line case—identical to the Flightmaster but a few millimetres smaller. The watch was offered with two dial variations: one displaying just "Seamaster 200," and the other, like this example, featuring the depth rating beneath. The acrylic bezel was always bidirectional, and the hands were enamelled black. Two different bracelets were available; more commonly, the watch is seen on the 1162 bullet bracelet, whereas this example comes on the rarer 1247 mesh.

The remarkable thing about this watch is that it has never been worn. Purchased by a Greek submarine officer, it was kept as a gift for a future grandchild. He eventually had only one grandson, who inherited the watch some years ago. It still retains some of its original protective film on the case and case back, as well as its original rubber dive extension—something we’ve never seen in person before. The original box is also present. The original wax seal on the caseback is still in place. 

The movement runs very well, but if the buyer intends to wear the watch, we are happy to facilitate a service at cost, as the oils and gaskets will need to be renewed.
