    I gave this watch to my boyfriend for Valentine's Day. It has a comfortable rubber strap and looks great. It's a great gift! Lots of payment options.

    In person, the watch looks even more impressive than in the photos. The gray dial paired with the black case gives it a very modern, "aviation" vibe. This is my first Gravitymaster, and I’m impressed by the build quality—you can tell it’s a premium model that will withstand literally anything. I really appreciate the Dual Time feature, because I travel often and having a second time zone displayed on the dial is super practical for me. As for the purchase—free shipping and the option to extend the warranty for another 3 years ultimately convinced me to choose this store.
