I do think it's an interesting complication. In a way, it stretches time, allowing us to see and live fractions of a second. The way Zenith designed it, it is useful since it is tied to the chronograph and not just a visual curiosity, altough it is also visually delightful.
I have some problems with the design of the Striking 10th/36000vph: date in the wrong place (should be at 4:30), wrong overlapping subdials (the upper subdials should overlap the lower one), lack of bezel, etc. Let's just say that if this movement were in a ChronoMaster, I would be more inclined to buy it. I would like to have one some day. As a Zenith fan, the Striking 10th and the Charlie Vermot 36000vph are special.

they succeeded. The older version has subdials that are too large.
I just wish they had kept the design details instead of changing them for the worse.





...the sub-dial obscuration is an issue....The big red hand is great, as you say, for reading fractions of a second without squinting. But due to the obscuration of the seconds subdial, some thought will be required for anything between 30 (ish) and 45 (ish) seconds....Perhaps it'd become intuitive? But perhaps not much fun at a place like Phillip Island... Then again, a split seconds feature is what you really want for timing laps....

I thought it might be intuitive given that they are keyed to each other and given that the overlap only really covers 15 odd seconds, you'd be out of the obscuration zone before the red hand had been around a little less than twice...
Thanks for the feedback. The 10th is probably the most interesting and useful chronograph out there, function-wise.
Last nit-pick! I despise little logos on the end of seconds hands...eeeech. At least the Zenith star is reasonably integrated and unobtrusive.

I replied to Art, but that reply is just applicable to your post. Your points are well made and well received. Makes perfect sense!
