Chrono all the way..
A watch that has lived a good, hard life thus far!
Simple Chronographs thus far, but I have been thinking about a Flyback.
I'm one of those weirdos that actually use the chronograph timing function quite often, at least several times a week, thus I also prefer non screwdown Pushers, but then there is the issue of water resistency. For all around timing, and robustness, as well as buttons that can be activated under water, I love Omega. AP and Panerai are very nice, but I'm not super comfortable with them in the water. Daytona is a tad on the small side (as far as pushers go)...
