For those of you who own both Zenith books, Rosler and Joel Duval, please advise which is more helpful and informative. Thank you.
For collecting purposes, I'd have to say the Roessler. Duval's is more of a narrative history than a catalog, of great interest to the Zenith aficionado, but not as good as the Roessler for assessing individual watches.
Thanks Lou, Roessler is on the way to me by tomorrow. That Amazon prime is fast. Btw, I have admired your Z collection through posted pics, and I congratulate you on building such a strong collection. I was Rolex my whole life, I have several, a few Omega too, but darn if I'm not bit hard by the two Z I have now! It's only the Z catching my attention these days!!! Mostly through your pics! Thanks!
