I think I may have found a new watch. I was at a very good watch store this weekend drooling at some fabulous watches. The one that caught my eye was the Breitling Chrono Avenger. I noticed that the pushers are not screw-down, so I am curious about whether they will be problematic if I swim/dive/shower, etc. Any thoughts? FWIW, I was quoted a price of $2500 for it (w/rubber strap).
