I received this in full set from first owner today. Now, bear with me: When I saw it on sale locally, I was torn, because of the Hublot, etc vibes it emits.
Looking at it from another perspective however, it is an El Primero in an unorthodox presentation. The execution is excellent, the dial looks far from cheap in light / under the loupe and the details are sharp, as one would expect from Zenith. On the functional side, it has a smooth, high-beat, running seconds hand and a chronograph option, which makes more sense in the real world then a full chrono.
Size is another concern, but that is an individual problem.
😀
At the prices that these can be bought occasionally, I think it is an intriguing value proposition. I came back from a surgery today and needed to reward myself with something smallish. In any case, I was skeptical before seeing it in the "flesh", but I am very happy with it.
