This Zenith Defy El Primero 21 checks that box and then some. I naturally appreciate any skeletonized dial or open caseback and this has that in spades. This titanium case is both beautiful, comfortable, and lightweight. The most innovative feature of this movement is it's "double-heart architecture". It features two independent escapements that operate at completely different speeds. While most watches beat at 4 or 5 Hz the seper is the ability to measure 1/100th of a second and the fact that the chronograph has it’s own system with it’s own gear trains, balance wheel, mainsprings, and something really unique is it’s own power reserve indicator. This "double-chain" architecture is necessary because the chronograph and the main timekeeping functions have very different energy needs. The 50 Hz Chronograph spins so fast that when you engage it and put it to your ear you can hear it hum. It also gets wound both ways. Clockwise winds the chronograph and you can watch the power reserve climb as you wind it...counter-clockwise winds the timekeeping mainspring manually, which is also handled by wearing the watch and allow the automatic rotor to wind the watch. This watch also has different materials besides the case. Zenith uses a Carbon-Matrix Carbon Nanotube composite for the hairsprings which is light, strong, and resistant to magnetism. This is an amazing piece of horology with a skeletonized dial that let you actually view the technology in the watch. It's amazing they put so much into the watch but the titanium case makes it wear and light and comfortable. CONDITION: This watch is in very good pre-owned condition.
