Quick TakeStrap yourself in for an adventure with the Stratoliner S-41 Cool Gray. This isn't just a watch; it's a piece of certified spacefaring kit refined for terrestrial exploration. The cool gray stardust dial feels like gazing into a nebula, punctuated by those functional blue Superluminova markings – a constant reminder of its orbital heritage. You feel the substance of the recycled steel case, a solid 41mm presence with a reassuring 98-gram weight, knowing it can handle pressures up to 200 meters deep thanks to that triple-gasket crown. Running the show is the Werk 17 manufacture calibre, a space-tested engine with a smooth column-wheel chronograph and a practical day-date, all backed by a hefty 60-hour power reserve. Adjusting the sturdy block bracelet using the slide clasp's micro-adjustment feels precise, engineered. It's a serious tool watch that doesn't shout, but confidently states its capability, ready for boardroom meetings or baja blasts.

DescriptionThe Fortis Stratoliner S-41, reference F2340007, presents specific engineering parameters commencing with its case dimensions. Fabricated from recycled stainless steel, the case measures 41 millimeters in diameter, exhibits a vertical height of 14.5 millimeters, and possesses a lug-to-lug distance of 50.5 millimeters. This housing is engineered for substantial water resistance, rated at 200 meters, equivalent to 600 feet or 20 atmospheres. Contributing to this rating is the screw-down crown mechanism, which incorporates a triple gasket system for enhanced sealing integrity against water ingress. Further sealing is achieved through the utilization of Performance FKM gaskets. Positioned atop the case is a Flat Orbit Bezel. The case back features a smoked sapphire crystal incorporating a distinctive space window element, allowing partial visibility of the internal mechanism. Protecting the dial is a sapphire crystal treated with an anti-reflective coating applied to both its inner and outer surfaces to minimize glare and maximize legibility under various lighting conditions. The watch head itself registers a weight of 98 grams. Chronograph functions are actuated via quickset pushers integrated into the case flank.

Internally, the Stratoliner S-41 houses the Space-Tested Automatic Manufacture Calibre Werk 17. This movement provides chronograph functionality utilizing a column wheel mechanism and incorporates day and date complications. It operates automatically and delivers a power reserve of approximately 60 hours when fully wound. The regulation adheres to chronometer standards, ensuring a high degree of timekeeping accuracy. Visual interface is achieved through the Cool Gray Stardust Dial, which features specific Space-Travel Markings treated with Superluminova X1 emitting a blue glow for low-light visibility. Luminescence via Superluminova X1 is also applied to the primary time-indicating hands. The hour and minute hands are rendered in black metallic finish, while the sweep second hand is distinctively colored space-blue. The chronograph counter hands maintain the black metallic finish for cohesive visual presentation. The timepiece is secured to the wrist by a Block Bracelet, also constructed from recycled stainless steel. Attachment of the bracelet links is facilitated by a screw pin system. Closure is managed by a stainless steel slide clasp featuring an integrated microadjustment system for precise fit customization.
