Nordhavën™ FKM Series Rubber Watch Strap

Nordhavën™ FKM Series

Engineered for the harshest conditions on Earth—and beyond—the Nordhavën™ FKM Series combines expedition-grade durability with timeless Scandinavian elegance. Crafted from high-performance FKM rubber, it offers unmatched resistance to extreme temperatures, saltwater, UV exposure, and mission-critical environments.

The dual-finish deployant clasp—mirror-polished at center, brushed at the edges—adds a sophisticated technical character worthy of both Rolex Submariners and Omega dive and space heritage timepieces. Offered in 20mm, this variant brings both comfort and rugged dependability to any adventure.

Whether you’re descending into cold depths, trekking through alpine passes, or navigating daily life with purpose, Nordhavën™ FKM is built to perform with confidence.

Nordhavën™ Color Palette

Glacial Black — A matte, glacial black that echoes the dark stone and icy debris carried by moving glaciers. Rugged, understated, and expedition-ready.. As dark as winter waters beneath a frozen fjord, Arctic Black embodies quiet strength, depth, and the clarity of exploration in its purest form.

Nordic Blue — A crisp, elegant blue drawn from the frigid open waters of the Norwegian Sea. Shadowy and refined, Nordic Blue mirrors the hues of deep-water diving, glacial melt, and the vast horizons where sea and sky blur into one seamless expanse.

Alpine Green — A muted, sophisticated green echoing snow-capped ridgelines, wind-swept pines, and the moss that clings to icy stone along high-altitude trails. Earthy yet refined, Alpine Green feels both natural and distinctly adventurous.

Note: the same colors in TPU and FKM colors vary slightly in hue. For instance, the green in FKM is a little lighter and more muted. Please reference the photos.

Designed for those who live between snow-capped mountains and deep fjords, Nordhavën™ is the ideal companion for cold-weather outings, maritime exploration, or everyday wear with a sense of adventure.

The Nordhavën™ Expedition Palette is shaped by the landscapes, seas, and frozen horizons of the far north. Each color reflects a different aspect of cold-water adventure and alpine exploration:

Alpine Green

A refined mountain green drawn from windswept ridges, conifer forests, and snow-shadowed peaks. Earthy and timeless.

Glacial Black

A matte, glacial black that echoes the dark stone and icy debris carried by moving glaciers. Rugged, understated, and expedition-ready.
