SIDEREAL CLOCKS

Precision Astronomical Timekeeping for Architecture & Luxury Spaces

Haute Horlogerie · Live Ephemeris Engine

Where Celestial Mechanics Converge with Interior Architecture

Engineered for monumental spaces, each Sidereal Horologe tracks true stellar time, the precession of the celestial sphere, and planetary alignment. From the flagship 600mm salon editions to bespoke 900mm architectural masterworks, our timepieces bridge prime meridian precision and living space. For transatlantic residences, our synchronised "Twin Clocks" orchestrate Northern and Southern hemisphere projections in simultaneous harmony.

Optical Clarity & Dimensional Depth

Synthetic Sapphire Crystal & Zero-Gap Display Bonding

Each dial is shielded beneath an edge-to-edge optical-grade mineral glass or synthetic sapphire crystal, treated with dual-surface vacuum anti-reflective nanocoating. Our proprietary optical-bonding process eliminates the internal air gap between the crystal and the dial plane, preventing internal refraction and delivering museum-grade clarity with zero glare from morning light to nocturnal ambient illumination.

Transmission 99.8% Zero Glare
Hardness 9 Mohs Scratch Impervious
Acoustic Damper < 12 dB Near-Silent
