All-Round Defense: These cases typically cover the sides, edges, and sometimes the display, utilizing raised edges (lips) to prevent the screen from coming into direct contact with flat surfaces.
Built-in ScreenMany guard cases include built-in, 9H tempered glass or a thin protective film to safeguard the fragile watch face without compromising touch sensitivity.
Material Variations: They are usually made from lightweight, shock-absorbing materials like soft TPU (Thermoplastic Polyurethane), hard Polycarbonate (PC), or durable metals.
Slim Profile: Designed to add minimal bulk, they retain the natural aesthetic of the watch and can often be installed easily (snap-on design) without taking off the watch bands
