MONOLITH ONE — Lume Edition
Contained light. Structural form.
MONOLITH ONE — Lume Edition integrates a photoluminescent core into a forged carbon structure.
By day, the design remains subtle and controlled. By night, the strontium aluminate core emits a soft, controlled glow.
No electronics. No batteries. Only material responding to light.
The forged carbon centerpiece is machined under high pressure, revealing a unique marble pattern on each piece — no two are identical.
Material integrity. Controlled illumination. Engineered simplicity.

- Measure your wrist just above the wrist bone.
- Use a flexible measuring tape. If you don’t have one, use a string and measure it against a ruler.
