I don't want to hijack the thread, but does the silver on silver and gold on gold theme apply to all omega watches from the 70s or is it possible to buy a watch with stainless steel case and gold elements on the dial. I bought a 166.0121 with a 1418 movement that has a SS case and a dial that is blue and brown(ish) Google only comes up with that combination for a gold case. Google is not definitive in these matters but it does make me wonder.
This your only warning, any future talk about not wanting to hijack threads around here will be dealt with most severely. 😒
Mine (cal. 750) .... purchased 2nd hand so don't know if it's original but it was into Omega for servicing and they said nothing about it not being original.
