Just sharing some new photos of this new (to me) watch. Very sharp case (literally!). It dates from 1963. Although the tritium is dead, the lume is quite photoluminescent (similar to my '57 Ranchero and '47 Suveran). Omega really rocked with their lume, almost Luminova-like in brightness; I can see it clearly all night (if I care not to sleep, I guess).
