Dude, the original poster forgot to mention that it’s an Apple Watch Ultra 2. Just a misunderstanding. But yes, it’s a genuine black titanium Apple Watch Ultra 2 as I can tell by the photo. By the way, if it’s been less than two weeks since you purchased it from the Apple Store, return to the store and exchange it. Bring your receipt or an email invoice (🧾) that shows you bought it from Apple and inform them that there’s a defective watch. An Apple Watch Ultra 2 purchased from the store should not have any marks like that.
