I own a few Breitling and Zenith and i personally think the Zenith are better made watches. My ElPrimo is now some 15 years old and looks brand new and i love the look of there latest line of watches. The El Primo is only 40mm in diameter and i now like the larger watches. I believe that Zeniths new line is around 45 - 48 mm in diameter.
As for Rolex i never owned one and new will, despite the fact they can cost $10,000 or more they look cheap to me
