Possibly a noob question but I notice when you look at lots of different images of the TV dial, some seem to obviously have a circular "inner-bezel" going around the TV shaped dial and connecting it to the TV shaped outer bezel. Like there is a little moon sliver on the sides and top of the dial. However, in a lot of other pictures I don't see these crescents. Were there two variants of this model (maybe one with an all black rehaut and one with silver rehaut?) Pictures where it's quite obvious: https://omegaforums.net/attachments/dscn0666-jpg.317756/ https://s-media-cache-ak0.pinimg.com/736x/83/ec/ba/83ecbab4bcec3640b260080f1137fd8a.jpg Pictures where it is imperceptible: http://image.noelshack.com/fichiers/2015/27/1435642811-2.jpg http://www.chronomaddox.com/omega/watches/speedmaster/176.0014/link/tight_740.jpg
It's called a rehaut. It's on all of them it's angle and lighting on why it looks like it's not there.
There's a lot of variations on these ... I do recall looking at a couple of examples a few years ago with the vague idea of putting together all of the Mk's in one place. Anyway, this http://www.chronomaddox.com/MarkSeries.html should be a good starting point for details on the different dials/rehautes and such. Best I can help, though I'm sure someone else will be able to give full chapter and verse shortly.
