Great shoe. Great style

Beautiful shoe. Nice quality. Going to reorder in a Wide. Regular runs too narrow for my feet. Hope the Wide works.

Great watch - looks good and keeps good time
I love this thing. Good for a big wrist. Lume holds well and the blue lume looks awesome with the white/blue theme. Holds writhing a couple seconds (2-5) per day, which is pretty excellent at this price point. Would recommend.
