Clamping Case Structure

The clamping case structure involves inserting the glass between the bezel and the case and clamping them together from underneath, which makes the watch more water-resistant.
Luna Arch is designed with the bezel placed on top of the glass similar to the bezel-setting technique used in jewelry-making. This structure exposes the rim of the sapphire crystal glass placed beneath the bezel so that it can be seen from the side across the entire circumference, giving it an airy look.
Meanwhile, Uruga features a structural design wherein the bezel, the glass, and the case are clamped together from both top and bottom using four separate parts, resembling how gemstones are set on pieces of jewelry.
