Hi guys, with love for watches, I had put one of mines (that one was non-Omega) under a macro lens for magnification, wanting to see some of its beauty more clearly. To my horror, on the blue-steel second hand of my multigrand 9-month-old 50-meter-resistance watch were many rusty spots.

The AD (after few questions) sent it away for further check...

I am wondering whether a low-level of water resistance in high humidity weather may play a role.
Any comments? thoughts?

Thanks for reading.
