Solid Timepiece
Color: Grey, Color: Grey
Overall, I’m really happy with this watch. The only small complaint I have is adjusting the bracelet. I picked up a $15 watch repair kit to size it myself, and while it wasn’t difficult, the push-pin links were definitely more of a hassle than I expected—especially compared to my Oyster bracelet with screws. Just a bit time-consuming, nothing major. Once that part was done, though, I’ve loved everything about it. It’s a great everyday watch, surprisingly accurate, and one of those pieces you just don’t get tired of looking at. For what it’s worth, this is coming from someone who also owns a Submariner—not trying to flex, and yes, I fully realize how douchey that sounds. Nothing screams “please validate my life choices” like bragging about an overpriced watch that basically just tells time. But in all seriousness, I only mention it to give some perspective on how much I genuinely enjoy this one.
