Capturing nature

The Black Sand Dial

Jan Mayen Black Sand unveils the battered coastline of Jan Mayen, with its foreboding beaches made of black volcanic sand. The dial's jagged ridges capture the underwater landscape of miniature dunes, shaped by the perpetual motion of water. Delicate vertical stripes spring to life under specific lighting conditions, showcasing nature's boundless creativity crafted with only two elements––sand and water.

We carefully sculpt every dial detail in CAD software and then CNC machine a series of stamping tools with increasing fidelity. These are then used to stamp brass blanks in multiple stages, adding finer and finer details. Next, we apply multiple coatings, lacquers and fumés to establish depth and dimension. A final layer of clear coat is polished to a glass-like finish, resulting in a truly captivating visual experience. 

The applied logo and indices ensure contrast and legibility, while the ultra-sharp diamond-cut hands complement the intricately finished watch case. Additionally, all elements are coated with applied Super-LumiNova BGW9 for optimal visibility.

Expedition-tested

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.

Expedition-tested

Case

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.

The movement

LJP G101

The Jan Mayen collection utilizes the LJP G101 by La Joux-Perret, renowned for its high level of precision and quality, as well as its 68-hour power reserve. The time-only display provides an uninterrupted view of the watch face. The movement is graded Soigné and adjusted to four positions, ensuring accurate timekeeping. The movement and engraved rotor are visible through a sapphire window screw-down caseback.

The packaging

The Capsule

Every Jan Mayen comes bundled with a Straum Capsule, designed to keep your watch protected against the elements and is machined from a single block of aluminium and surface treated with a HA1 Hard Anodization process to increase durability.⁠

"As a long-time fan of both Fratello and the microbrand scene at large, I really dig this latest LE with Straum, a brand that hit my own radar with their previous Opphav line."

“It's all about that dial. It's very unique.”
"It's amazing. I love it. It's like Grand Seiko, but evil."
"The blue [dial] that transitions from a bright azure blue to deeper, darker hues at the edges is simply mesmerizing. The casework is solid, with sharp transitions and attention to detail, like radial brushing on the bezel."
