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.

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.

Islander Black DLC Aviator Automatic Watch with Leather Strap and an Anti-Reflective Sapphire Crystal #ISL-46

Owners widely praise the Islander Black DLC Aviator Automatic Watch with Leather Strap and an Anti-Reflective Sapphire Crystal #ISL-46 for its anti-reflective sapphire crystal, legible dial, and strong C3 lume. The Seiko NH35 movement, featuring hacking and hand-winding, is also a commonly cited positive, contributing to its value at a $199 sale price. Some owners appreciate the clean, unbranded dial, aligning with traditional Flieger design. However, one owner notes the watch runs fast, requiring frequent time adjustments, and another commenter feels the date complication detracts from the Flieger aesthetic.
