The build
Black Open Heart Nautilus is an open-heart — the balance wheel left visible through a cut in the dial, finished in black.
Power comes from a Seiko NH35 automatic. Every unit goes through the same routine: movement regulated on the timegrapher, crown and gaskets checked, crystal reseated, hands aligned against the markers, then a 24-hour run on the bench.
Nothing here is render-only: the photographs are of the actual unit from this batch. Want a different dial, bezel or bracelet before we start? Say so in the enquiry — most swaps add nothing, some add the part cost, and we quote before building.
AuraMod builds on new aftermarket cases and Seiko-compatible movements. Model names describe the style of the build — we are not affiliated with, endorsed by, or acting for any watch brand.
