Confident daily protection - with an aluminium alloy, military-grade frame

Aluminium-alloy construction adds rigidity around the watch bezel, absorbing knocks and resisting deformation. Reinforced edge geometry reduces impact transfer to the display.

Rugged casing keeps the watch safe during active use, while remaining slim enough for everyday wear. Owners can tackle outdoor activities without worrying about dents or big scuffs.

Cleaner screen and reliable touch response - thanks to Armorite glass and oleophobic coating

Armorite glass protectors adhere precisely to the display surface and include a fingerprint-resistant oleophobic layer. High transparency preserves display clarity and the glass chemistry keeps touch sensitivity intact.

Touchscreen gestures feel natural and responsive, while fewer fingerprints make the display easier to read. The dual protectors give a ready spare for replacements or rough use.

Fast, bubble-free installation - with special epoxy resin adhesion

A specially formulated epoxy resin promotes strong, even adhesion and naturally expels trapped air during application. The adhesive cures to create a secure bond without manual smoothing.

Users can fit the protectors with minimal fuss and a clean finish, cutting down installation time. Accurate cutouts and matched colour keep the watch looking original after fitting.
