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

Where have these watches been?
Color: Grey on Black Fabric
A wonderful looking and wearing (with some wee modifications)watch. I originally bought this watch with the textile band but soon discovered it was not a marriage made in heaven. I swapped the bracelet for a leather aftermarket deployment bracelet and it transformed the watch for me.
