Fortis Marinemaster M-44 DLC

Ref. F8120031
Diver

The Fortis Marinemaster M-44 DLC is widely praised for its robust COSC-certified Kenissi Werk 11 movement, offering a 70-hour power reserve, and its stealthy, scratch-resistant Dianoir DLC coating. Owners find it comfortable to wear despite its 44mm size, with one owner considering it a standout piece. Some reviewers note a subtle difference in the color tone of the DLC coating on the crown and bezel lock between variants. Overall, owners and reviewers regard the Fortis Marinemaster M-44 DLC highly for its durable construction and reliable, high-spec movement.
