The date 14.703 and non-date 14.702 only came with the 552/562 in 1959 and 1960, maybe a little into 1961. There were several iterations of each, going up to -5 or -6 I think. Before that in the mid to late 50's, there were models with the 47x, 49x and 50x (ie: 2892 = 503) calibers inside that were nearly identical, but Omega was switching the model numbers from 4 digit to 5 digit during the late 50's (1958?). There were even nearly identical watches but with manual wind calibers from the 28x series inside. The last was the 14.726 in 1961 which looked exactly the same as the 14.702 - the only difference on the dial was the lack of the word "AUTOMATIC" of course.
Overall, this style of Genève was made from around 1954 to 1961. Originally these were to be the manual wind high end non-chronometer counterpart to the automatic Constellations, but after 2 or 3 years Omega made automatic non-chronometer versions of the Genève too. I don't recall if there were chronometer versions but if there were they'd be very rare.
