I've got a problem with Breitlings (I've somehow ended up with several versions of the Navitimer, Steelfish, and Evolution). They're all great watches. If you're looking for a big, bold chrono, it's hard to beat Breitling's Chronomat Evolution (BCE). The navitimer is a nice, classic look, but it's smaller (41mm I believe, vs the over 43mm BCE). Also, the Navitimer does not come with double sided ar - a dead giveaway in a Breitling rep, as the gens are heavily coated with anti-reflective coating. The Steelfish Superocean (SFSO - or SOSF?) is nicely done too, but it's not a chrono.
If you do end up getting the BCE, stick to the "ultimate" versions. Some of the dealers' websites still show the v1 BCEs; these have inferior (1 sided, I believe) ar, and the wrong color subdial hands (black, should be silver). The grey/black, graphite, and black/silver are the only colors in ultimate (if I'm wrong, please someone chime in). IMO, you might want to get one with the stainless steel (ss) bracelet, and buy a black croc-patterned strap with deployant buckle separately. If you do get the strap, get one without the holes in the long end. Get the one in the pics below. It should cost $35 or so.
Good luck.
