Best purchase ever
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.
