I have a soft spot for the "technical" dials on the Geneve's/Seamaster de Ville's from the early sixties. I'm not sure "technical" is technically correct, though Omega refers to one of these at least as Zifferblatt Technic here:

In any case, I have three of these and two just came back from the watchmaker. The last one needs some more serious work, but I thought I'd share some pics anyway.
First is an ST 131.019 geneve with the wonderful cal 601 handwound movement. As you can see from the picture below, the dial is very similar to the Seamaster 600 (135.011) shown above, though mine has an even simpler dial (which is one of the things I like about these watches).
Next up is a "proper" seamaster ST 166.002 with the (also lovely) automatic 562 movement. As you can see, this one shares some features with the Geneve above in terms of its dial layout. Note, however, the two dots at the 12 o'clock marker similar to those seen on the speedmasters.
Finally, I picked this one up in a pretty beat up condition and haven't sent it off for mending yet. It's a Seamaster 600 (ST 135.011, cal 601) like the one in the ad above. But it has the speedie-like dial that's given it its nickname Speedmaster Companion. It's certainly not a perfect example, but I'll still be happy once I get a new crown and crystal on it - and replace the movement with a much better looking 601 that I have in my drawer.
I am astonished by the large amount of dial variations Omega made to watches in these series. Some are quite dressy, others more flashy and some quite simple. If you have other examples of these series, please feel free to post here.
Thanks for looking.
