Looks exactly as pictured
Color: Gold
Bought this as a graduation gift for a sons friend who admired a similar one on vacation with us. He really liked it and it is a nice entry level dress watch for those who like to collect them. It was easy to adjust the band with a personal watch kit and was heavier than I expected.

⭐⭐⭐⭐⭐ Clean Look, Comfortable Ride
Size: 11.5 Wide, Color: Woodbury Handstain
The Cole Haan Men’s GrandPro Tennis sneakers are a perfect mix of laid-back and polished — the kind of shoe you can wear everywhere without thinking too hard about it. Right off the bat, the design is subtle but refined. They’re minimalist enough to pair with jeans and a hoodie, but they also work with chinos and a button-down for a more put-together look. The “tennis” aesthetic keeps it classic without feeling like you’re wearing athletic shoes. Comfort is where these really shine. They’re lightweight and cushioned in all the right places, so long walks, errands, or standing around at events don’t end with sore feet. There’s no stiff break-in period — they feel good from the first wear. The sole has just the right balance of support and flexibility, which makes them easy to wear all day. The materials feel good too — soft, sturdy, and not flimsy. They hold up well after repeated wear and still look fresh even after a few outings. They don’t crease or scuff up excessively, which is always nice. If I had to point out a downside, it’s that they’re not performance sneakers for athletics — but that’s not what they’re meant to be. They’re lifestyle shoes that look great and feel great for everyday wear. Overall, a solid go-to sneaker that elevates casual outfits and keeps comfort front and center. Easy recommend if you want versatile kicks that stay stylish without being loud. I was able to pick up this particular pair here on Amazon for 50 bucks, 56 total with everything and honestly I’m still scratching my head in that deal. I mean my New Balance were 70 bucks or something like that. These are brown leather, sophisticated and comfortable, just amazing shoes. I get compliments all the time.
