Fortis Marinemaster M-44 Ocean Blue Ref. F8120021. Professional Swiss dive watch featuring the Manufacture Werk 11 Chronometer movement, 70-hour power reserve, Fortis Lock System® bezel and 500m water resistance.
Built for those who refuse to stay on shore.
The Fortis Marinemaster M-44 Ocean Blue is not a watch designed for display cases. It is a professional instrument created for explorers, adventurers and those who trust their equipment when conditions become unpredictable.
Its distinctive Ocean Blue accents capture the spirit of the open sea, while the robust 44mm recycled stainless steel case is engineered to perform in the harshest environments. Whether on a diving expedition, at sea or in everyday life, the Marinemaster inspires confidence through strength, precision and reliability.
For more than a century, Fortis has built watches for professionals, pilots, astronauts and explorers. The Marinemaster continues this tradition beneath the waves.
At its heart beats the Manufacture Werk 11 calibre, developed with Kenissi and certified as an Official Chronometer. Offering an impressive 70-hour power reserve, it delivers the precision and dependability expected from a modern Swiss tool watch built without compromise.
Powerful, purposeful and unmistakably Fortis, the Marinemaster M-44 is made for those who seek adventure rather than attention.
