Fortis Stratoliner S-41 Gravity Black Edition Automatic – F2340018

Please note the price does not include tax & duties.

The FORTIS Stratoliner S-41 Gravity Black is a professional-grade timepiece built for pioneers who demand endurance, precision, and striking design. Featuring the first-ever DLC-coated case in the Stratoliner collection, this 41mm chronograph pushes the boundaries of toughness with a hardened matte graphite black finish milled from recycled stainless steel. The coating achieves a remarkable hardness of up to 4500 Vickers—nearly 20 times stronger than standard stainless steel—delivering unmatched resilience in any environment.

Its stardust-textured dial evokes the vastness of space, enhanced by bold space-travel markers and black metallic hands filled with Superluminova® X1 for exceptional legibility in all conditions. A space-blue sweep second hand and luminous accents add a distinctive edge, while a smoked sapphire crystal case back with a “space window” reveals the movement within.

At its heart beats the space-tested Manufacture Calibre Werk 17, a chronometer-grade automatic movement featuring a column-wheel chronograph and day-date complication, offering an impressive 60-hour power reserve. Engineered with a screw-down crown, triple gasket system, FKM gaskets, and 200m water resistance, the Stratoliner S-41 Gravity Black is built to perform under pressure—whether in the cockpit, the stratosphere, or everyday life.

FORTIS has designed the Stratoliner Gravity Black as more than a watch—it is a mission-ready instrument, blending innovation, endurance, and refined clarity for those who live ahead of their time.
