Nice watch
Color: All Gold
Great watch! Looks nice and could tell it was made very well. The only down side is it can be easily come un clipped while on your wrist.

Could not be happier. :)
Color: Blue Dial & Two tone strap, Color: Blue Dial & Two tone strap
I am in love with this watch, I went to a jeweler to have the band sized, as soon as I handed it to him I was given a compliment by the jeweler on the watch :) I did expect the face of the watch to be a bit bigger, but this is in no way a complaint! It really does have a nice weight to it, and I love the leather case it came in, really nice to keep the watch in when not wearing it like at night, or the shower. Beautiful craftsmanship!
