Seikonaut Skeleton Watch – An openwork Aquanaut Seiko Mod.
This build represents the heart of Seiko modding culture — clean lines, open architecture, and refined proportions. At its core beats the NH72 skeleton movement, a gold-tone automatic caliber prized for its exposed mechanics and smooth reliability.
The case draws inspiration from the Patek Philippe Nautilus, with integrated lugs and sharp transitions, reinterpreted with high quality Seiko Modding Parts. It’s a watch that doesn’t try too hard — instead, it lets the details speak: precision-fit components, a skeletonized dial, and purposeful contrast.
A stunning alternative to Artisans de Genève watches for sale online — at a fraction of the price.
