Very good watch, but I would have liked it to be bigger, about 43 mm, a little difficult to read.

Excellent Watch
Color: Gold Silver-G8408
I don't know why this watch is getting a less than perfect rating from others. I purchased this watch legit to make sure my son got out of the shower at the gym on time to get where he is going. LOL It is classy, elegant and yes, has been exposed to sweat, water and soap extensively, and still looks fantastic. He is getting the black one next.
