I live in Florida where, during the endless summer, one will work up a sweat just walking outside to get the morning paper. We run our air conditioning here 24/7 for eight months out of the year, and frequently during the other 4 months. As you will see from my collection, I go for durable, water resistant watches, almost always on bracelets or rubber dive straps. I tried leather straps on several of my watches, but when they get sweated on regularly they become uncomfortably "moist" and turn nasty before long. I have the same problem with NATO straps.
Is this just me, or do other fellow southerners have a problem with leather straps?
