Quick TakeStrap this Stratoliner S-41 Blue Japan to your wrist and feel the connection between terrestrial craftsmanship and celestial ambition. That Blue Japan Stardust dial isn't just a color; it's a slice of the final frontier, sprinkled with Superluminova® X1 that glows like distant nebulae. The heart ticking beneath is the Werk 17, a manufacture calibre that's literally earned its space legs, boasting chronometer precision and a useful 60-hour power reserve alongside day-date and column-wheel chronograph functions. Housed in a tough, eco-conscious 41mm recycled steel case rated for 200 meters, it’s ready for adventures both earthly and imagined. From the satisfying click of the quickset pushers to the smooth operation secured by FKM gaskets and a triple-gasket crown, every detail screams capability. Even the German-made, vegetable-tanned Aviator strap speaks volumes about quality and sustainability. It's more than a watch; it's a robust, reliable companion with a cosmic soul, built for those who look up and wonder.

DescriptionThe Fortis Stratoliner S-41, reference number F2340017, presents a case constructed from recycled stainless steel, possessing a diameter measurement of 41 millimeters. Its structural integrity ensures water resistance rated to 200 meters, equivalent to 600 feet or 20 atmospheres. The case incorporates a Flat Orbit Bezel design element. Examination reveals a lug-to-lug dimension of 50.5 millimeters and a total height profile of 14.5 millimeters. The watch head component registers a weight of 98 grams. Sealing is achieved via a screw-down crown engineered with a Triple Gasket System, complemented by quickset pushers for chronograph operation. High-performance FKM gaskets are utilized throughout for enhanced environmental resistance. Protecting the dial is a sapphire crystal treated with anti-reflective coating on both its internal and external surfaces. The case back features a smoked sapphire crystal display, designated as a space window, allowing observation of the internal mechanism. This configuration balances robust engineering with material consciousness, utilizing recycled steel for the primary case structure while maintaining significant depth tolerance and operational security through advanced gasket and crown systems. The precise dimensions offer a substantial yet wearable profile on the wrist.

Powering the Stratoliner S-41 Blue Japan is the space-tested automatic manufacture calibre Werk 17. This movement provides chronometer-level regulation, ensuring high accuracy. Its integrated complications include a column wheel chronograph mechanism and a day-date display. The movement architecture supports a power reserve of approximately 60 hours. Visually, the timepiece features a distinctive Blue Japan Stardust Dial, accented with gray Superluminova® X1 Space-Travel Markings for low-light visibility. Luminescence across the dial elements emits a blue glow. The hour and minute hands are executed in black metallic finish, filled with Superluminova® X1. The sweep second hand is differentiated by a red center section and white Superluminova® X1 application. Chronograph counter hands are rendered in a coordinating black metallic finish. The watch is secured to the wrist via an Aviator Strap, crafted from vegetable-tanned cowhide leather, double-folded without extraneous filling materials, emphasizing sustainable production methods and handmade German quality. Attachment to the case is facilitated by a screw pin system, ensuring secure mounting. The strap terminates in a stainless steel folding clasp mechanism for reliable fastening and ease of use. Every component, from the intricately detailed dial to the sustainably sourced strap and the rigorously tested movement, contributes to the overall functional and aesthetic specification profile of this instrument.
