NAUT MOD - CHOCOLATE (OPEN HEART) Rosé Gold

The Naut Mod Chocolate Open Heart in Rose Gold is the most visually complex piece in the Naut Mod line. A warm chocolate dial with a cut-out at 6 o’clock exposes the oscillating balance wheel of the Seiko NH38 — not a display case back trick, but a true open-heart aperture cut directly into the dial. Rose gold accents on the hands and indices pull the warm tones together into something that feels genuinely considered. The integrated 316L stainless steel bracelet follows the Naut Mod’s Nautilus-inspired silhouette: case and bracelet flow as a single piece rather than two parts bolted together.

Why open heart?

An open-heart dial does two things at once: it tells the time and shows the mechanism doing it. The NH38 runs without a date wheel, so the balance wheel sits centred under the aperture rather than offset. On a chocolate dial with rose gold detailing, the result is warm, mechanical, and hard to look away from. Every Naut Mod Chocolate Open Heart is hand-assembled by MedoMods in Germany, tested before shipping, and delivered from within the EU — no import duties, no customs delays.
