Hi Haakon,
The chrono pushers on the Daytona screw down when not in use for water-proofing. When unscrewed they are firm and flawless. The Omega SeMPC has nice, firm tight pushers that don't screw down but water-resistant nonetheless. Both great examples of modern chronographs - different, but both work perfectly and are highly recommended. If considering a chronograph and want to spend less money (a nice thing) I like the Tag Heuer Carrera - another classic and beautiful watch with the proven Valjoux 7750 movement. Best of luck on whatever you choose.
