Naut Mod - Tiffany (Open Heart)

The Naut Mod Tiffany Open Heart is where bold colour meets mechanical theatre. Built in the integrated-bracelet sports watch style, it wears the distinctive light-blue Tiffany dial as a canvas — and then cuts an open-heart aperture straight through it, exposing the NH38 front mechanism beneath. The result is a 41 mm Seiko Mod that earns a second look from across the room and holds attention up close. Hand-assembled by MedoMods, it is aimed at anyone who wants a conversation piece that still runs on a rock-solid Japanese movement.

Key Specifications

• Adjustable integrated stainless steel bracelet with butterfly safety folding clasp – sits flush with the case for that seamless sport-luxury silhouette

• Case back: exhibition window – watch the rotor spin

Why This Mod Works

The open-heart window is not a gimmick — on the NH38 it frames the visible front mechanism at dial level, turning every glance at the time into a reminder that a real mechanical movement is at work. Paired with the Tiffany blue dial, the contrast of vivid colour and raw movement creates depth that printed dials simply cannot match. The integrated bracelet completes the premium feel: no gap between case and bracelet, just a clean continuous line. Shipped with EU pricing. Within the EU, no import duties and no import VAT apply.
