Seiko Mod Nautilus – Gold Skeleton Watch with Green Strap

This Seiko Mod Nautilus delivers maximum presence with its full gold-tone case and skeletonized dial architecture, contrasted by a rich green rubber strap. Powered by the NH72 automatic skeleton movement, this build opens up the entire mechanical structure — showcasing the balance wheel, gear train, and bridges in motion.

Unlike a traditional Seiko dial, which conceals the movement beneath, this openworked layout transforms the dial into a display of mechanical depth. It’s an ideal alternative for builders who want their mod to reflect the inner workings of the watch, not just its surface.

Engineered for NH72, this build integrates seamlessly with premium Seiko mod parts produced by us, offering tight tolerances, full visibility, and a modern sports-luxury silhouette. The green strap introduces a playful but refined contrast — making this a great choice for those who want color without sacrificing elegance.

Inspired by the spirit of high-end skeleton creations from brands like Parmigiani Fleurier, this Seiko-based build delivers serious watchmaking energy without the six-figure price tag.
