Totally different design.
Hard to explain in words. Better seen in action.
The chrono pusher is a 3 piece design.
Upon unscrewing there is an outer sleeve of the pusher that either retracts or covers the pusher button completely. Beautiful piece of engineering and concept and much more expensive to execute. Although I agree it is a bit big but when you see it in action you'll understand why.
I asked and got the answer from no less than their designer that the pusher design follows the pushers on Seiko's timing watches used for the Olympics, meant for repeated use and no jump when triggered. The function overrides the aesthetics.
The Daytona pushers are a 2 piece construction (no outer sleeve) and less robust in comparison.
They are similar to the other screwed down pusher designs on the older Omegas and TH. No doubt being smaller they look more proportionate. Being small and more delicate, repeated screwing and unscrewing of the pushers' locks will see the threads wearing out. Ask Donald..
The old one look like oversize Rolex pusher, don't they?
