Quick TakeForget sterile lab equipment; this Fortis Stratoliner S-41 is pure, distilled cool adventure strapped right to your wrist. That Cool Gray Stardust dial isn't just gray – it's the color of lunar dust captured under a spaceship's landing lights, speckled with the promise of the unknown and lit by that distinct blue Superluminova glow, like distant nebulae. The recycled steel case, a solid 41mm block, feels substantial, earned, like it's already orbited Earth a few times – because its movement has been space-tested. Inside beats the Werk 17, a proper manufacture engine with a crisp column-wheel chrono ready to time anything from a spacewalk to your coffee brewing, plus a handy day-date for keeping track of terrestrial appointments. The flat orbit bezel and space-blue chrono hand are subtle nods to its cosmic credentials. Secured by that German-made Aviator strap, it's rugged yet refined, equally ready for mission control or a weekend escape. This isn't just a watch; it's a tangible piece of aspiration, built tough, designed sharp, and powered by a heart that's literally out of this world.

DescriptionThe Fortis Stratoliner S-41, reference F2340015, presents a case constructed from recycled stainless steel, measuring 41 millimeters in diameter. Its vertical dimension, or height, is recorded at 14.5 millimeters, while the distance between the lug extremities spans 50.5 millimeters. Engineered for resilience, the watch head registers a weight of 98 grams. Water resistance is rated to 200 meters, equivalent to 600 feet or 20 atmospheres, ensuring capability in aquatic environments. This level of protection is supported by a screw-down crown employing a triple gasket system and performance FKM gaskets throughout the construction. The case features quickset pushers for chronograph operation. A flat orbit bezel design frames the dial aperture. Protecting the dial is a sapphire crystal treated with anti-reflective coating on both its upper and lower surfaces. The case back utilizes a smoked sapphire crystal, incorporating a design element referred to as a space window, offering a view of the internal mechanism.

Powering this timepiece is the Space-Tested Automatic Manufacture Calibre Werk 17. This self-winding movement incorporates a column wheel chronograph mechanism, considered a premium feature for precise start, stop, and reset actions. Integrated complications include both day and date displays. The movement guarantees a power reserve of 60 hours when fully wound. Its regulation meets chronometer standards, signifying high accuracy. The visual interface consists of a Cool Gray Stardust Dial, accented with blue Superluminova® X1 space-travel markings for enhanced low-light legibility. The primary luminescence compound used across the dial and hands is Superluminova® X1, emitting a blue glow. Hour and minute hands are rendered in black metallic finish and filled with Superluminova® X1. The central sweep second hand is distinctively colored space-blue and also features Superluminova® X1 application. Sub-dial counter hands maintain a consistent black metallic finish. This model is paired with an Aviator Strap, meticulously crafted from vegetable-tanned cowhide leather, double folded without unnecessary filling material, sourced from sustainable production, and handmade in Germany. Attachment to the case is achieved via a screw pin system, and the strap secures with a stainless steel folding clasp.
