This watch is my daily driver. It offers all the bells and whistle for a price point that anyone can work hard and obtain. I do have a wild collection (wild to me. Near 200k in combined value) I can’t count the number of times someone’s asked me hey that’s a cool looking watch or is the the AP on rubber strap. In both instances people are shocked that you can get so much quality at this price point.

Look and feel awesome!

Size: 11.5, Color: Optic White/Opti

These are awesome shoes - look great really, really white and clean! Love how comfortable they are - and soooo light. I was a little worried they'd get dirty easily, but I've been able to keep them clean. Fit as expected. If you're looking for a great, comfortable, and affordable shoe, check these out!

Great shoe, comfort

Size: 11.5, Color: British Tan/Ivry

Love these shoes, they're super comfy. Laces stayed tied all day. I wear them in a business casual environment, or if I'm going out for a nice meal with my wife. They look good, the color is unassuming and neutral. they also elevate my height, I feel like it gives me an inch or so more versus regular shoes. This is my second pair!
