More than a watch — a personal mechanical instrument. A timepiece that carries a memory, a love song, a wedding melody.

Interactive · The Comb & Cylinder
Run your finger across the comb.
Inside Lyra, a rotating cylinder's pins pluck tuned steel teeth — exactly like the instrument below. Hover or drag across the teeth, or let the cylinder play the Lyra motif.
Beyond Grandeur's standard melody library, clients may submit any song. Grandeur transcribes it, prints the cylinder in metal, and your music becomes a horological component.
