Is chronograph pusher feel a matter of mechanics alone or does taste also enter the equation?
Take the CH 29-535.
The start/stop pusher has a distinct break point that requires a decent amount of pressure to overcome.
By contrast the reset pusher presents almost no resistance at all, with no discernible break point.
Contrast this to the Lange 951.x movements, where both the start/stop and reset pushers have distinct, light, break points - but the pressure required to activate the start/stop pusher is considerably less than required for the Patek.
Are these differences purely mechanical or do manufacturers have different tastes when it comes to pusher actuation?
I do wonder whether Patek prefers a more deliberate start/stop feel to Lange, as based on the smoothness of the Patek’s reset pusher I do suspect they could go for a more Lange-like feel if they wished to.
