SEIKO MOD ATELIER · EST. 2024

Nothing here left the factory this way.

KAMEN AUTOMATIC · 24 JEWELS

21,600 vph — the seconds hand steps six times a second. That's the NH35A beating, not a render.

THE COLLECTION

Built, photographed, and numbered one at a time.

A mod is only as good as the seal you can't see.
— Workshop rule no. 1

ASSEMBLY ORDER

Seven parts, stacked in the only order that works.

Numbered because the sequence is real — skip a step and the crystal won't seat.

    AFTER IT ARRIVES

    Keeping a modded automatic alive.
