Complete Your Build

The Nomods Nautilus is a 40 mm solid-dial Seiko mod watch built on our Nautilus-style platform — the solid-dial counterpart to the Nautilus Skeleton. The 316L stainless steel case sits just 9.95 mm thick, giving this watch an ultra-thin profile that wears closer to a dress watch than most Seiko mods. Inside, the Seiko NH35 automatic movement delivers hacking, hand-winding, and a 41-hour power reserve. Sapphire crystal up front, integrated steel bracelet with the signature Nautilus-style links, and 50 m water resistance round out the build.

Available in Blue, Rose Gold, and Green

Blue — sunburst navy dial

Deep navy sunburst with cobalt shifts in angled light. Pairs the cleanest dress aesthetic with the Nautilus integrated bracelet — the most versatile of the three colourways.

Rose Gold — warm pink-gold finish

Soft pink-gold case treatment with a matching sunburst dial. The dressiest of the three colourways, and the one Spanish-language searchers ask for as oro rosa.

Green — sunburst forest dial

Forest-green sunburst dial with subtle olive undertones; a less-common Nautilus colourway with quiet character.

Compatibility

This is a fully assembled watch built on the Nautilus platform. The modular design allows component swaps:

Hands: Pre-installed Nautilus-style hands — Replaceable with any NH-series compatible hands, such as the Royal Oak V1 Silver Hands.

What's Included

Fully assembled Nomods Nautilus watch in your selected colourway
Integrated stainless steel bracelet (pre-installed)
Watch box

The Nautilus 40mm is our own take on the integrated-lug, sport-luxury silhouette. The case is CNC-machined from 316L stainless steel, brushed and polished by hand, and the integrated bracelet flows directly from the lugs — no spring bars, no break in the line. The 9.95 mm thickness keeps the watch slim and wearable for daily use, and the 30.8 mm dial opens up the broader Nomods dial catalogue for future builds. Every watch is checked individually before shipping.
