  • Classy!
Color: All Black-Black
Got this as a gift for my husband, it fit perfectly! You can adjust it accordingly, but luckily, we didn’t have to. My husband loved the classic look, he plans to wear this more than his Apple Watch. Loved how prime was available, arrived fast!

  • This watch has a good weight and feel
Color: Gold-Tone
This watch has a good weight and feel. The only issue is with setting the date. In order to get it to be exact you need to set it right at midnight wen the day changes otherwise the date will be off. Other than that it keeps the date and time well once you have it set properly.
