Quick TakeThe Marinemaster M-44 Ocean Blue isn't just a dive watch; it's an underwater instrument. That robust, recycled stainless steel case houses a powerhouse, the Werk 11 chronometer movement, promising precision even when the ocean's depths get extreme. The intense 500m water resistance laughs in the face of pressure, while the Fortis Lock System® on that Gear Bezel means your settings stay put, no matter the underwater chaos. And that O-patterned dial, glowing with Superluminova®X1, is a beacon in the abyss. The Horizon Strap of resilient, hypoallergenic FKM is the strap of pure function. This is a watch built to survive, built with precision, and made to take a beating underwater. It is not just a timepiece. This Fortis is a tool you will want to depend on.

DescriptionThe Fortis Marinemaster M-44, reference F8120021, showcases a robust construction centered around a 44mm case diameter, meticulously fashioned from recycled stainless steel. This material choice underscores a commitment to sustainability without compromising structural integrity. The case exhibits a height of 14mm, contributing to its substantial presence, and integrates a screw-down crown fortified by a triple gasket system. Further enhancing its underwater capabilities, performance FKM gaskets are utilized, ensuring optimal sealing and resistance against environmental factors. The watch head registers a weight of 102 grams, an indication of its durable build. A lug-to-lug measurement of 48mm determines the overall wearability and fit on the wrist.

Protecting the dial is a sapphire crystal, treated with an anti-reflective coating on both sides to maximize legibility under various lighting conditions. The dial itself is black, featuring Fortis's signature O-pattern, and displays applied indices filled with Superluminova®X1, emitting a blue luminescence for enhanced visibility in low-light scenarios. The metallic hour hand and an orange-accented minute hand, both treated with Superluminova®X1, facilitate time reading. A metallic sweep second hand, featuring a Superluminova®X1 filled "Bull's Eye" indicator, completes the dial layout. The watch incorporates a bidirectional Gear Bezel with the proprietary Fortis Lock System®, providing secure setting and operation. Powering the Marinemaster M-44 is the automatic manufacture Calibre Werk 11, a certified chronometer movement, indicating a high level of accuracy and precision. This movement features a date complication and delivers an ample 70-hour power reserve. The case back is constructed from stainless steel and features ultra-engraving. The F8120021 model is presented on a Horizon Strap, crafted from hypoallergenic FKM rubber, selected for its resilience to heat, chemicals, and UV radiation. A stainless steel folding clasp secures the strap, and a screw pin system is used for strap attachment. The watch holds an impressive 500m (1640ft, 50atm) water resistance.
