I've been carrying a 1923 Illinois Bunn Special daily since I got it about two months ago. It has a Rose Gold filled case with some moderate brassing around the edges.
I'm a little concerned about how the summer heat might affect the watch. I don't carry carbon steel bladed pocket knives in the summer because my perspiration soaking through my jeans causes them to corrode rather quickly. Stainless steel blades hold up just fine on those sweaty days.
How would my watch hold up under these conditions? Should I refrain from carrying it on hot days to avoid damage?
