Zenith presents Chronomaster El Primero Full Open.

The classic chronograph with a skeleton dial, in both 42mm and a retro 38mm size. The larger watch has a slightly larger date wheel to maintain the proportions. Notably, the skeleton date wheel on the 38mm has a more refined look, having thinner numerals.  Both the 38mm and 42mm models are available in stainless steel or steel with an 18k pink gold bezel.
