TRIHEX LINE — Lume Edition
Three lines. Integrated light.
Part of the LINE Collection, the TRIHEX LINE — Lume Edition integrates three luminous inlays into a solid forged carbon structure.
Parallel strontium aluminate cores are embedded directly within the carbon plate, remaining subtle in daylight and emitting a controlled glow in low light.
No electronics. No battery. Only material responding to light.
Each forged carbon plate reveals a distinct marble pattern formed during forging. No two pieces are identical.
Structural repetition. Controlled illumination. Engineered restraint.

How to Measure Your Wrist
- 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.
- Keep it snug — not loose, not tight.
- Do not add extra space. We include a comfort allowance in the bracelet design.
