From time to time I see people ask about the size of 5135 if its too big....Here's a wrist Pic on my skinny 6.4" wrist :
It sure is a nice addition to my Big watch collections
My AD order the strap for me, It's not a OEM strap. The thickness is 4.5mm down to 1.5mm.
Hope this help.
How a watch looks on one's wrist is totally personal taste. IMHO, the 5135 looks too big on you and overwhelms your wrist. OTOH, if you like it then what do you care what others may think?
