I do not know how much I like the P before I owned it. The heft of 5131/1P makes me feel like a man. I tried to take 5131/1P off from my wrist, but I put it on my wrist again after I tried different model of watches.

Two 5131/1P on the wrist is too heavy for sure.

I changed my 5131R strap too. I enjoy new strap very much.
