that's definitely Zenith's modern classic. I like the guilloche dial version, too.
Would be nice if Zenith brings back the cal. 420 (manual wind) and cal. 410 (full calendar and moonphase), and a modern interpretation of the cal. 135.
. . . for a revised chronometer movement based on the cal 135, and the surprise offering this year based on the cal 5011K is giving me hope that it will eventually come to fruition.
