Capturing nature

Jan Mayen Dials

The dials capture the stunning natural beauty of Jan Mayen, encompassing the black volcanic sand beaches, vividly colored rocks, resilient mosses, and the fiery basaltic lava interior of the volcano Beerenberg. Each texture is carefully crafted and transformed into a series of stamping tools, progressively increasing in fidelity. The dials are stamped in multiple stages, layered with metallic coatings to add a sheen, infused with fumé colors, and finally coated with a glossy finish, resulting in a truly captivating visual experience.


Integrated bracelet

The bracelet is specially designed to endure the harsh conditions of the Arctic with its custom-engineered structure. It is made from Stainless Steel 316L and features a seamless integrated design that tapers from 24.8mm to 18mm at the buckle, ensuring a comfortable and snug fit on your wrist. The push-button butterfly clasp is custom-designed and seamlessly integrated, providing a sleek and secure closure for the bracelet. The two 130% links also allow for a precise and tailored fit to your wrist. Whether you're out in the wilderness or in the city, this bracelet is built to last and will withstand even the harshest environments.



The watch case combines durability, functionality, and aesthetics. It is crafted from 316L stainless steel, which provides resistance to corrosion and wear, ensuring long-lasting performance and reliability. With a diameter of 39mm, it offers a comfortable and practical size for everyday wear. The sunburst bezel frames the double-domed sapphire crystal, which provides exceptional scratch resistance and ensures crystal-clear visibility of the dials. The grippy screw-down crown ensures that the 10ATM water resistance is maintained.
