Quick TakeWitness the F-39 Liberty Blue. It's not just a watch; it's a commitment, sculpted from recycled steel and radiating a cool, confident aura. The vertically brushed blue dial, framed by that purposeful 12-hour bezel, gives it a ready-for-anything vibe. The Superluminova® X1 isn't just functional; it's a statement, glowing green in the dark. The UW-30 automatic movement, while hidden, is the heart of this beast, ticking away with reliable precision. It's a tool watch that doesn't scream for attention but quietly commands respect. The solid weight, a comfortable presence on the wrist and is secured with the robust block bracelet, gives a tangible assurance of build and finish quality. The F-39 Liberty Blue isn't trying to be flashy, it's confidently capable, perfect for someone who appreciates precision without pretension.

DescriptionThe Fortis Flieger F-39 Liberty Blue, designated by the reference F4220023, represents a robust and meticulously engineered timepiece. Its case, constructed from recycled stainless steel, measures 39mm in diameter and exhibits a lug-to-lug distance of 50mm, contributing to its substantial wrist presence. Case thickness is precisely controlled at 12.5mm. The bidirectional 12-hour bezel, also crafted from stainless steel, features half-hour increment markings, facilitating the tracking of a second-time zone. An examination of the case back reveals a solid stainless-steel construction, detailed with ultra-engraving. A screw-down crown, employing a triple gasket system and augmented by Performance FKM gaskets, ensures a noteworthy water resistance rating of 200 meters (600 feet, 20 atm). The watch head alone weighs 79 grams.

Protecting the dial is a sapphire crystal, treated with an anti-reflective coating on both inner and outer surfaces to minimize glare and maximize legibility under diverse lighting conditions. The dial itself features a vertically brushed blue finish, adding a touch of visual texture. It sports an applied, circularly brushed "Brixtrack®", adding a layer of detail. Application of Superluminova®X1, on the white "Brix" indices and the "Synchroline®", enhances visibility in low-light environments, emitting a signature green glow. The hour and minute hands are metallic, also incorporating Superluminova®X1 for low-light visibility. Similarly, the sweep second hand is metallic, featuring Superluminova®X1. The core of the watch's functionality is delivered by the automatic Performance Calibre UW-30, providing the essential timekeeping functions and a date complication. This movement, regulated to chronometer standards, boasts a power reserve of 38 hours. The included block bracelet is made of recycled stainless steel, matching the case material. The bracelet incorporates a stainless-steel slide clasp, featuring an integrated micro-adjustment system. The bracelet is joined to the case by a screw-pin system.
