Parmigiani claims a world first novelty with its Tonda PF Chronograph Mysterieux.
On first glance the watch appears to be a time only 3-hander with central seconds.
But activating the monopusher at 7:30 transforms the watch to a 5-hand chronograph.
The 1st press of the monopusher "zeros out" the rhodium plated hands transforming them into chronograph hands and starting the measurement of elapsed time. Simultaneously, the hidden gold hands are revealed and continue to show the time.
The 2nd press of the monopusher stops the chronograph.
The 3rd press of the monopusher resets the rhodium plated hands to the time and hides the gold hands until the chronograph is activated again.
In this example, you can see that the chronograph was activated 36 seconds before the photo. The chronograph hour and minute collector hands are still at zero. The time, shown on the revealed gold hands, is 1:56.
This is a highly legible 12-hour chronograph with no subdials or perimeter scaling.
When not in chronograph mode, the watch is a clean, crisp, integrated bracelet sport watch with Parmigiani's typical understated luxury aesthetic.
The newly created caliber, PF053, is highly complicated with 60 hours of power and beating at 28,800 vph. The new caliber is beautifully finished, a real feast for the eyes.

I will attempt to post a video of the chronograph in operation. In the meantime, I'd be interested in your thoughts on this novelty from Parmigiani.
