Quick TakeStrap into something truly stellar with the Stratoliner S-41 Cosmic Gray. This isn't just a watch; it's a mission timer born from recycled steel, ready for terrestrial adventures or maybe even a zero-G jaunt. The 41mm case feels purposeful, grounded by its 98-gram weight and secured by a robust block bracelet also made from recycled materials – talk about sustainable exploration! Its heart, the space-tested Werk 17 manufacture calibre, beats with chronometer precision, offering a hefty 60-hour power reserve and the utility of a column-wheel chronograph plus day-date. But the soul? That's the Cosmic Gray Stardust dial, sprinkled with blue Superluminova X1 markers that glow like distant nebulae. Look closer through the sapphire crystal – anti-reflective, naturally – and let the space-blue seconds hand sweep you away. With 200 meters of water resistance and a screw-down crown, it's as ready for splashdown as it is for liftoff. It’s an instrument with iconic style and serious function.

DescriptionThe Fortis Stratoliner S-41, reference F2340008, features a case constructed from recycled stainless steel, presenting a diameter of 41 millimeters. Its structural integrity is engineered for significant environmental resistance, offering water resistance rated to 200 meters, equivalent to 600 feet or 20 atmospheres. The case height measures 14.5 millimeters, and the dimension from lug tip to lug tip is 50.5 millimeters. Encircling the dial is a Flat Orbit Bezel. Securing the case back is a smoked sapphire crystal exhibition window, designated as a space window, allowing visual inspection of the internal mechanism. Operational water resistance is further enhanced by a screw-down crown employing a Triple Gasket System and performance FKM gaskets throughout the assembly. The chronograph functions are activated via quickset pushers. Protecting the dial is a sapphire crystal treated with anti-reflective coating on both its surfaces to maximize legibility under various lighting conditions. The weight of the watch head alone is specified at 98 grams, contributing to the instrument's substantial presence without the bracelet.

Internally, this timepiece houses the Space-Tested Automatic Manufacture Calibre Werk 17. This self-winding movement incorporates a column wheel chronograph mechanism, providing precise start, stop, and reset functions for the timing complication. Additional functionalities include displays for both the day and the date. The movement operates at chronometer-certified levels of accuracy and provides a power reserve of approximately 60 hours when fully wound. The visual presentation is defined by the Cosmic Gray Stardust Dial, which incorporates Space-Travel Markings applied using blue Superluminova X1 for low-light visibility. Luminescence is a key feature, utilizing Superluminova X1 with a distinct blue glow across relevant indicators. The hour and minute hands are rendered in black metallic finish, also treated with Superluminova X1. The central sweep second hand is finished in space-blue and features Superluminova X1 application. Chronograph counter hands maintain a consistent aesthetic with a black metallic finish. The watch is paired with a Block Bracelet, constructed from recycled stainless steel matching the case material. Attachment to the case is achieved via a screw pin system. The bracelet terminates in a stainless steel slide clasp which includes an integrated micro-adjustment system for precise sizing.
