The Casio G-Shock Carbon Core Guard GA-2110SU-3ADR is a men's watch known for its durability and rugged design. The watch features a mineral crystal, which is a type of hardened glass commonly used in watches. While not as scratch-resistant as sapphire crystal, mineral crystal is still quite durable and offers good protection for the watch's display. The watch has a water resistance rating of 200 meters (20 bar), making it suitable for various water-related activities, including swimming and snorkeling. The watch has an analog-digital display, meaning it features both traditional analog watch hands and a digital display for additional functions and information. The strap is likely made from a durable and flexible material, such as resin, commonly used in G-Shock watches.
