He Acted Like He Didn’t Care… Now He Wears It Everywhere
Color: Gold Steel
I bought this watch for my husband for Christmas (his birthday is right before), and he loved it! At first, he acted like he didn’t care, but now he wears it all the time—whether he’s dressing up or just going out. It really completes his look. It was a little big at first, but we had it adjusted and now it fits perfectly. Overall, it’s a very nice, stylish watch. Very happy with this purchase!

Can't beat this price and quality!
Color: Silver/Gold
This is my first Amazon review, and I must say how impressed and happy I am with this watch! I've owned this same exact watch before, but sadly I lost it last year. I was reluctant to pay the full original price of $275, so I decided to chance it with Amazon, and I couldn't be happier with my choice. Having owned this exact model before, I feel very confident I can spot a real vs. fake MK watch. It met almost all the criteria to determine that it's real. Here are the positives and negatives: Criteria to determine authenticity: - Model number (MK-8344) matches original and is included on the back of the dial - The Michael Kors logo is featured on the dial. - The font of the letters is consistent with the official brand logo - The spacing is even, and that the quality of finish is high. - Came in original Michael Kors box where one edge is broader than the other, with a clear writing of ‘Michael Kors’ on it. - The lid was wider and bigger than the box, covering a major portion of it, meaning it's authentic. - The Michael Kors logo is included on the top of the box in fine and clear text. - The box has a batch stamp located on the bottom. - “All Stainless Steel” at the top in a semicircular pattern along with the model number. - Original MK logo embossed on the crown - Has three sub-dials with three different number values (a fake MK watch will have subdials that showcase the same values.) - Displays date with a proper alignment inside the window (in a fake watch, the display is disputable and unaligned) Negatives: - No warranty booklet included. - No extra link included Although it didn't meet every expectation, you still can't beat the quality and price. A part of me thinks that most of the 1-2 star reviews are from people who have a vested interest in seeing you pay full price, so they leave negative comments to scare you into going to Macy's or MK directly. Don't let them fool you. This watch appears to be genuine, and even if it's not, it's the best damn fake I've ever seen.

LOVE LOVE LOVE
Color: Gold Steel, Color: Gold Steel
My husband - the one to the right. Has had this for about 4 years now. I'm coming to write a review because the battery just went out and I'm wanting to repair It for him for this Father's Day trip. As I'm looking in the nooks & crannies I'm noticing that I purchased this back in 2019/2020 something like that - (can't go back and check or I'll lose this message ) BUT IT LOOKS GOOD! Yes It is needing a good wash, and I seen on YouTube a reg toothbrush and dawn soap will help with that. But wow this looks great after all this time. I'll post a pic of what It looks like now. He only wears It when he's dressed, he doesn't wear It daily but here is what It looks like with no cleaning whatsoever
