Let us get into the small minute differences significant to building hype...
😉
Let us talk chrono pushers. From what I have seen there are three types - the all yellow, the all red and the red and yellow:
Mine - all yellow.
All red - pic stolen from net (jds1017 photobucket).
The red and yellow - also stolen (chrono shop net).
The versions with one colour seem to correspond with the watch being of the earliest execution - with dials without dots at 12. Low serials - mine starting with 2913. One can imagine that Omega later decided on having one version of the pushers - fitting both colour chrono hands, thus started with the two colour pushers.
I have also found information, on a German site, that the service pushers of the two colour version has a larger indention than the originally fitted. Can anyone verify this?
