Watch Crystals/Clock Glasses TRIZ Cases

A two-glass recess filled with connecting material secures decorative settings, absorbs impact, and maintains a watertight watch glass.

Full-height gasket contact resists high water pressure during deep diving by preventing dislodgment of the seal.

A silica-based antireflection film with controlled porosity enhances optical clarity and antifogging properties for precision timepieces.

Segmented windshield glass with varying curvatures reduces refraction distortion, enhancing visibility of hands and scales.

Matching refractive index between liquid and movable part slows rotation speed, creating a slow-motion visual effect without mechanical constraints.

Titanium oxide and silicon oxide layers form an antireflection film that reduces light reflection on watch cover glass.

An aspherical lens in a timepiece crystal expands the angular range of clear visibility beyond traditional spherical designs.

A polycrystalline ceramic substrate with a PVD functional coating resolves the trade-off between manufacturing ease and mechanical strength.

Continuous recesses in watch glasses simplify production and reduce thickness while securely holding gemstones.
