Size up! Twice!
Size: XX-Large, Color: Black
Nice jacket, but runs VERY small. I sized up from an XL to a 2XL and it still is snug.

Great watch
Color: Blue on Blue Rubber
Beautiful watch with great value for price and very comfortable. Only issue is the brightness of the dial in the dark, it's very low and can be difficult to read when it's dark out. Other than that I have no notes
