I am sharing my mint 70s Zodiac Chronograph GMT with Valjoux 72 movement and Pepsi bezel. The watch is actually a re-branded Heuer 2446C GMT. Everything is identical except for the brand name.
and the value...if it was branded Heuer it would be worth almost 3X more. Nice looking piece regardless.
Very similar indeed ... ... well, very like the Mark 4 generation I mean . Previous dial and/or case are slightly different though. I guess you know the OTD website already (?) Anyway, it's a very nice watch you have there. Congrats !
