Quick TakeStrap on the Stratoliner S-41 Cosmic Gray and feel the pull of something beyond the everyday. This isn't just a timekeeper; it's a piece of engineered resilience, born from recycled steel and tested against the rigors of space. That Cosmic Gray Stardust dial isn't merely decorative – it's a tiny universe on your wrist, punctuated by blue Superluminova markings that glow like distant nebulae in the dark. The heart, the Calibre Werk 17, isn't just automatic; it's a manufacture chronograph movement, a complex machine with a robust 60-hour power reserve and chronometer precision, ready to time terrestrial or imagined zero-G maneuvers. With 200 meters of water resistance secured by performance gaskets and a triple-gasket crown, it laughs off Earthly splashes. The Aviator strap, crafted from sustainable, vegetable-tanned cowhide, adds a touch of classic pilot cool, grounding the space-age tech. It’s a statement piece that carries the legacy of exploration, blending rugged specs like the 98-gram watch head weight and 14.5mm height with a design that looks simultaneously forward and back.

DescriptionThe Fortis Stratoliner S-41, reference F2340016, presents a case fabricated from recycled stainless steel, measuring 41 mm in diameter. Its structural integrity ensures water resistance rated to 200 meters, equivalent to 600 feet or 20 atmospheres. The case design incorporates a Flat Orbit Bezel. Dimensional specifications include a lug-to-lug distance of 50.5 mm and a total height of 14.5 mm. The watch head alone contributes 98 grams to the overall mass. Sealing mechanisms feature Performance FKM gaskets and a screw-down crown employing a Triple Gasket System, enhancing environmental resistance. Chronograph operation is facilitated via quickset pushers. Visibility of the dial is provided through a sapphire crystal treated with anti-reflective coating on both its internal and external surfaces. The case back is constructed from smoked sapphire crystal, offering a view designated as a space window into the movement within. Attachment of the strap or bracelet is achieved using a screw pin system for secure mounting.

Internally, the timepiece is powered by the space-tested automatic manufacture Calibre Werk 17. This movement provides chronograph functionality managed by a column wheel mechanism, alongside day and date complications displayed on the dial. It operates with a power reserve rated for 60 hours and adheres to chronometer regulation standards for timekeeping accuracy. The dial itself is presented in Cosmic Gray, featuring a Stardust texture and specific space-travel markings rendered in blue Superluminova® X1. Luminescence for low-light visibility is applied using Superluminova® X1, emitting a blue glow. The hour and minute hands are executed in black metallic finish, filled with Superluminova® X1. A distinct space-blue hue characterizes the sweep second hand, which is also treated with Superluminova® X1. Correspondingly, the chronograph counter hands maintain a black metallic finish to complement the primary time indicators. The overall aesthetic and functional design adhere to established iconic principles associated with the Stratoliner series.
