The blue really does pop! More choices to make now! BW, Chi Kai
with first glance they looked like VC overseas chronoβs!
The bracelets look cool, also the blue accented dials. Black on black ceramics could be really good ( if only the had stayed with white lume. With the black lume the hands and the indexes of the ceramics model play hide and seek as I could see in the Paris popup store. Choices, choices,..... Well done, Zenith! Best, Martin
Is the "chrono power reserve" label a misnomer? Presumably what's measured by the reserve de marche is the power reserve of the entire watch, not merely the chrono mechanism. Nice looking watch, though. The steel bracelet version seems to draw from the Royal Oak angularity, but still nice nonetheless, and it seems dissimilar enough to have its own identity. Cheers, John
The El Primero 21 actually houses two movements in one. You have the time movement which is automatically wound and has a balance that beats at 5Hz (36.000bph) And then you have a manually wound Chrono movement with its own balance beating at 50Hz (360.000bph) and a power reserve of something more than 50 minutes. The power reserve indicator shows the pier reserve of this latter Chrono movement. Best, Martin
