Welcome to TRF, Sargeinaz
Straps on Rolex are a nice change from the traditional looks, I suppose. I do like the looks of it, but I for my part would rather have a metal bracelet on my Rolex, be it SS (or SS/YG or YG if I had a Rolex to match it), the reason being that I do not like the way leather becomes sticky in hot weather when you perspire.
But it is always a matter of personal preference
