Isn't that what the Explorer II is for? I haven't worn any of my beater watches since I got my Sub...it performs perfectly for hiking, fishing and other outdoor tasks.Nice collection, and seems well thought out, although that Patek chronograph seems rather large to wear with a suit, no? I also have one of those Luminox watches on an army green NATO strap that I wear doing yard work and other outdoor stuff. Certainly not "SF approved", but it's good for that purpose.
