AFAIK there is only one type of gold dial (concerning the "background" of the dial) - only the markers and Omega logo are different - either yg or pink...
Erich This one is Rose Gold Case/Rose gold Dial/Rose Gold markers, No? I am wondering about Rose Gold Case/Yellow Gold Dial/Rose Gold markers 2500-
Yes, It's unusual, but they do exist ! I had one with the rarer "Omega Centenary" inscription recently but it is now sold because the movement was too far gone unfortunately. I will try and find a picture and post it later...
maybe this dial looks rose because of the aged lacquer - may have caused this tint... I must have a look on mine (ref 2500, cal 333) - in the bank vault... will let you know
This one never even reached the forum but it did have a very crisp case and yellow gold dial with rose gold markers and case!
My observation is that there are 3 dial types: YG background with YG markers YG background with RG markers RG background with RG markers The RG background with RG markers that I have seen are the last 2500s produced with the cal. 333 movement.
