Very satisfied with my purchase, the quality is incredible. Customer service was also amazing!
Got this for my boyfriend. He thought it was a Rolex at first 😎 Looks and feels amazing.

The transparent back is such a flex. Looks custom, feels luxury.
Was skeptical but the weight, shine, and finish are all top notch.
