Should really have a countdown clock for time between when 120 bezels hit the market. I don't think I've seen one this year.
The 135.027/165.027/565.007/566.007 original color variants were black on black, red on red, orange on black, and green on green. The 166.0073 in the 70s introduced the blue variant
The coloured variants seem very scarce. I don't recall seeing many examples at all - perhaps they were made in a very limited production run? I saw a blue bezel here on a 136.027 which looked genuine https://m.ebay.com/itm/OMEGA-SEAMAS...374600?hash=item2140a373c8:g:RD0AAOSwdhlbEj72Purchases made through these links may earn this site a commission from the eBay Partner Network
