First I want to say I am really digging this community! Zenith is simply my brand. With three Zenith and one on the way - with one additional (reverse panda) that I want - it is the largest number of watches from the same brand in my humble collection...Beyond the amazing modern watches, I am also stoked to see so many Rainbows and other late 80's to 1999 watches being shown...I am drawn to the now legendary caliber 400 that powered the Rolex Daytona during that now famous 12 year run.
Today I am wearing my newest Zenith acquisition - which I have not stopped wearing since getting it this past Thursday lol.
Mark IV De Luca technically pre-Rainbow, but this example was around as some of the first Rainbows were introduced. My first legit, no-colour panda. For the dollar - I do not know where or what brand with Zenith's horological significance - that you can get a panda (period) especially using a movement that powered a (detuned) Daytona.
