NAUT MOD - BROWN (OPEN HEART)

Warm tones meet mechanical transparency in the Naut Mod Brown Open Heart — one of the most characterful pieces in MedoMods' integrated-bracelet sports watch line. The brown dial already adds a vintage-inflected warmth that sets it apart from the sea of blue and black sports watches on the market. Add an open-heart aperture that frames the NH38 balance wheel in motion, and you have a Seiko Mod that works as a conversation piece as much as a daily wearer. This is handmade watchmaking with a personality.

Features

• 41 mm stainless steel case – integrated lug design, bold octagonal profile
• Automatic Seiko NH38 movement – hacking seconds, hand-winding, ~41 h power reserve, visible through open-heart aperture
• Sapphire crystal with Super-LumiNova – scratch-resistant glass, lume on hands and indices
• Screw-down crown & 5 ATM water resistance – rain and splash proof for everyday use
• Adjustable stainless steel bracelet with butterfly safety folding clasp – stays locked on the wrist
• Case back: exhibition window or solid steel – watch the rotor from the front and the back, or keep it clean

Why It Works

The open-heart complication turns the NH38's balance wheel into a dial feature — you see the oscillation at 21,600 bph every time you glance at the time. Brown dials have a heritage appeal that reads differently depending on the light: warm chocolate in sunshine, rich tobacco indoors. This combination of finishing and transparency is rare at this price point and only possible because MedoMods assembles every watch by hand in Germany, selecting and fitting components individually. Shipped within the EU — no import duties, no delays.
