I think you know what the front looks like, here's the back with a Preik caseback installed. Zenith EP Rainbow Flyback.
Yup. I was looking for one for a GMT Master and saw a few Zenith ones. The one drawback is it adds about 2mm to what would otherwise be a relatively thin watch. Must say, it's significantly more interesting than the Rolex.
Just arrived home after our travels, this little Certina KF320 from 1945 was the first to make a break for freedom. Sorry archive image
I love this watch, but there's something about the coloured subdials that for me seems to detract from the pristine beauty of the "classic", it's not resolved though, I'm currently following a moon to mars on E-vade
Have you seen one in the flesh ? I'm one of its biggest advocates but I'm aware it's not everyone's cup of tea...
