Yeah! The watch is really impressive...

The concept of the 96 series movement was to make a smaller movement but they really wanted a longer power reserve. The original target was around 72 hours. But it couldn't be done without a huge accuracy problem. So they compromised it to 65 hours. It's also important to note, the watch runs at 28,800 VPH! Not at 21,600 VPH like the Patek Philippe 240 caliber. So it's not cheating by using an extra small balance wheel and a low beat. No, it uses an appropriately sized balance wheel for the fairly high beat. The higher the beat rate, the smaller the balance wheel has to be. Overall, this actually means this movement is fairly sporty - sporty watches prioritize a smaller balance wheel and a faster beat. The smaller balance wheel has lower inertia, which means unfortunately it can get shocked more easily (so boxing lessons would shock the watch a lot and ruin the accuracy). BUT, the faster beat means that it would eventually recover from the shock faster than a slower beat. Hence why you see clocks with huge balance wheels and very slow beats. As long as the clock isn't shocked, the clock should be fairly accurate. Overall, I approve of this movement. Chopard is not cheating - some brands cheat by putting in a tiny balance wheel and a huge power barrels or two power barrels, and combine that with a slower 21.6K beat. Then that watch would be even more inaccurate! You've got an easily shocked watch and a slow beat that means it'll recover slower.
