Just returned from the Gym. I usually remove my Seamaster or Daytona, prior to entering the sauna or steam room. I have always thought the lubricants and oil will get too hot inside the watch. Today i met a gentleman, wearing his steel / gold submariner in both the steam and sauna for over 50mins. Apparently he has been doing this for the past 5 years without any problems with his watch.
I was wondering about anyone else's thoughts?
