The ØSTERSØEN Fuldmåne – A Dive into the Luminous Nordic Night
We’re proud to announce the launch of our newest timepiece: the ØSTERSØEN Fuldmåne – our first model with a full lume dial, inspired by the silent glow of the Nordic full moon above the sea.
When Darkness Reveals Time
Built for Adventures, Styled for Everyday
The Fuldmåne continues the legacy of our ØSTERSØEN dive watch collection. With its 39mm stainless steel case featuring our signature MØRK finishing: a hand-applied black-polish that gives the surface a subtle, refined contrast, this watch is made to be both durable and elegant. It’s water resistant to 200 meters, has a flat sapphire crystal with anti-reflective coating, and comes on a comfortable FKM rubber strap or our steel bracelet.
No Gimmicks, Just Time
Like all NMI watches, the Fuldmåne follows our principle of clean Nordic design: less is more. There's no date window, no distraction – just pure functionality and timeless style. Designed to be your companion on a hike through the fjords, a dive into cold northern waters, or a night out in your favorite shirt. With a compact 40mm diameter and a slim profile of just 11.5mm, the ØSTERSØEN Fuldmåne wears exceptionally well on any wrist, balanced, unobtrusive and comfortable for everyday use.
A Dial That Glows Through Time
The ØSTERSØEN Fuldmåne features a full lume dial coated with vintage-tinted Super-LumiNova®, glowing in a warm green hue once the lights go out. It’s not just a functional tool for low-light visibility. It gives the watch a character rooted in nostalgic dive watch design. Paired with hand-applied indices that are mirror-polished using our signature MØRK finish, the contrast by day is just as stunning as the glow by night. The polished markers catch the light at every angle and disappear into the dial in the dark, giving the lume full stage presence. The result is a dial that’s both sporty and minimal.
The Bracelet With On-The-Fly Adjustment
The ØSTERSØEN Fuldmåne comes equipped with a stainless steel bracelet that’s as functional as it is refined. With a 20mm width at the lugs tapering down to 16mm at the clasp, the bracelet offers a sleek, comfortable fit that hugs the wrist naturally. Each solid link is fully articulated for smooth movement, and the integrated on-the-fly adjustment lets you quickly fine-tune the fit, perfect for changes in temperature, activity, or just daily comfort.
So if you’ve been waiting for a watch that glows with the spirit of the North, now’s the time.
