What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Fortis Marinemaster M-44 DLC

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.

Fratello

Monochrome

Phoibos Leviathan

Owners widely report the Phoibos Leviathan offers a vintage experience at an affordable price due to its proportions and conservative design. However, the watch is considered well-made and sturdy but quite heavy, with a 45mm x 54mm lug-to-lug case and a 15.5mm thickness, leading some owners to replace the stock band. On balance, owners rate the Phoibos Leviathan highly for its vintage feel and sturdy build at its price point.

From video reviewers

The watch features 500m water resistance and a Seiko NH35 automatic movement. The case size is a point of contention, with reviewers noting it is substantial and may overwhelm smaller wrists, while others highlight a 40mm case size as an improvement.
