My high level question is what type of watch band is most comfortable and performs best for wearing during hot weather with occasional exposure to water? For example, imagine living in southern USA during summer without air conditioning for half the day day and with A/C the remainder. So that one experiences a range of comfortable/uncomfortable temperatures each day. Also imagine weekend camping and wanting to take a shower while wearing your watch in order to kept it close by, such that the band will occasionally get wet.
My favorite strap material from a looks and comfort point of view is leather, but I do not think it works very well under these conditions. I have tried some cheap rubber straps but never found them comfortable. I have mostly been wearing a nylon (Nato) straps for the scenario described above. I like the nearly endless color combinations and I frequently change straps to keep things interesting. They dry pretty quickly if gotten wet, though I will sometimes take them off after showering and towel dry in order to accelerate the process. But the annoying aspect is that the relatively widely spaced punch holes in the strap do not provide enough leeway to adjust once the weather gets extra hot and sweaty. Where the weather is so hot one is tempted to remove their watch, but does not want to do so. Only about 2 holes are useful in a punched strap, one tight and one loose, though sometimes a third extra loose hole will be tried to get extra relief and an ill fitting watch.
Which brings me around to the question of metal (stainless steel) bands, might this type of band be a better option? The style with larger links and a micro adjustment (e.g. diver) or the fine/stiff mesh with lock down clasp for a different approach to micro adjustment. Up until now I had dismissed wearing any type of metal bracelets after a unsatisfying experience years ago with a cheap digital watch. But do their water resistance and potential for adjusting make them a better solution?
I have a couple of Perlon straps that should work better than the Nato, but I have not used them under these conditions yet. Perlon is my next attempt but I am wondering if perhaps metal is the better solution for hot and/or wet conditions?
