LINE ARC — Forged Carbon Edition
Curved form. Pure material.
Part of the LINE Collection, LINE ARC introduces a continuous carbon silhouette shaped through precision and restraint.
Machined from solid forged carbon fiber and finished entirely in-house, the arc profile softens the linear language of the collection while maintaining structural clarity.
The gloss surface reveals the natural marble pattern formed during forging. Each bracelet carries a distinct carbon structure — no two are identical.
Controlled curvature. Material focus. 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.
