Quick TakeThe Fortis Flieger F-43 Bicompax isn't just a watch, it's a statement. This recycled steel titan, with its Liberty Blue dial, feels like captured sky on your wrist. The vertically brushed dial texture, combined with the Superluminova®X1 on the hands and markers, make it seem to shimmer. The 43mm case is no shrinking violet, while the integrated, micro-adjustable bracelet ensures a secure, comfortable fit. The UW-51 calibre humming inside offers both a chronograph and a date, but it’s the overall boldness that’s truly captivating. The F-43 is a robust timekeeping instrument that is built and looks like a tool. This isn't a delicate dress watch; it's a pilot's companion, ready for anything. It's a statement of purpose, a testament to rugged capability, built for those who are serious about time.

DescriptionThe Fortis Flieger F-43 Bicompax, reference F4240012, is constructed around a substantial 43mm case crafted entirely from recycled stainless steel. This case exhibits a height of 15.5mm and a lug-to-lug measurement of 54mm, resulting in a pronounced presence on the wrist. The watch head itself weighs 118 grams, contributing to the overall robust feel. Case integrity is reinforced through a screw-down crown, which utilizes a triple gasket system for enhanced water resistance. Additional sealing is achieved with Performance FKM gaskets throughout the case construction. Protection for the dial is delivered by a sapphire crystal, treated on both sides with an anti-reflective coating to maximize legibility under various lighting conditions. The case back is composed of stainless steel and features what Fortis terms "Ultra-Engraving." Water resistance is officially rated at 200 meters (600 feet, 20 atmospheres), denoting its suitability for professional marine activity and serious surface water sports.

The dial of the F-43 Bicompax showcases a vertically brushed blue finish. This textured backdrop is complemented by an applied circular brushed "Brixtrack®." Critical dial elements, including white "Brix" and the "Synchroline®," are treated with Superluminova®X1, a luminescent material that emits a green glow in low-light conditions. The hour, minute, and sweep-second hands are fashioned from metal and also incorporate Superluminova®X1 for visibility. Similarly, the counter hands are metallic. Powering the watch is the UW-51, designated as an "Automatic Performance Calibre." This movement delivers a power reserve of 48 hours when fully wound. Beyond timekeeping, the UW-51 provides a chronograph complication and a date function. Fortis indicates that the movement is regulated to chronometer standards, indicating a high degree of accuracy and precision in timekeeping. The watch is presented on a "Block Bracelet," constructed from recycled stainless steel, matching the case material. The bracelet utilizes a screw pin system for securing links. The closure is a stainless steel slide clasp, which incorporates an integrated micro-adjustment system for precise fitting to the wearer's wrist.
