Extra comfort without losing durability.
Gum might be a ton of things. It can be sturdy, scratch safe, however a few people have whined it's not precisely agreeable. So how could Casio settle that? They could make the band Leather, yet when it's late spring that truly adheres to your skin. They could make it out of material… But that wouldn't be as sturdy…
Thus, Casio chosen giving its clients the best of both universes! The outside of the band is a strong calfskin, which won't tear by and large. Within is an agreeable material, which feels smooth on your wrist.
While they were grinding away, Casio chosen to change the bezel also, making it aluminum rather than the ordinary tar. This makes the watch sparkle!
To ensure that your watch won't endure any accidents, regardless of what band it has, Casio ensured that this watch is stun safe up to 100m. That implies neither a knock, nor a fall, will prevent this watch from working!
You can even swim with the watch, since it has 200m water resistance! Not any more agonizing over anyone taking your watch!
