CATHEDRAL — A SKELETON-GEAR MOVEMENT FOR YOUR WRIST

The inside of a grand clock, ticking on your wrist: a full gear train, a balance wheel breathing at your seconds, and Roman numerals on an ivory dial. Every wheel turns. Nothing is decoration.

A REAL MECHANICAL MOVEMENT

- Working escapement train — center, escape and winding gears, all phase-locked and turning in time
- Balance wheel with a fine hairspring, beating with your seconds
- Breguet-style polished hands with a ruby second hand
- Roman numeral chapter ring on an aged engine-turned dial

FOUR INSTRUMENT COMPLICATIONS

- Heart rate, temperature and battery in beveled instrument wells
- Step counter that reads naturally: 990 → 1.2k → 12k
- Date window in a brass pill at twelve

THREE FACTORY SCHEMES

- Ivory (Verde) — cream dial, brass gears, sepia ink
- Ebon (Nero) — black dial, gold gears, cream ink
- Brass (Rosso) — warm brass dial, dark ink

MAKE IT YOURS

- Motion modes from the watch: full train, balance only, or still
- Show or hide each complication
- Bright interactive mode plus a quiet always-on look

BUILT FOR WEAR OS

- Native Watch Face Format, light on battery
- Requires Wear OS 5+ (Pixel Watch, Galaxy Watch and other Wear OS watches)
