What makes or breaks the Chronomaster Open is whether or not you're a fan of the "open heart" aesthetic on the dial. My understanding is that Zenith was the first to bring a watch link to market with this style of exposed escapement, influencing countless other brands in the process. I personally struggle a bit with the concept, but link I appreciate how Zenith has gone out of its way here to make the naturally asymmetrical dial layout a bit more aesthetically link consistent than on previous generations.

You link can see the problem. I think things have definitely improved since then in terms of general understanding of George link Daniels' escapement, but the whole link rationale for adopting it at Omega is still definitely worth looking at.
