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.

Hamilton Jazzmaster Open Heart Auto

The Hamilton Jazzmaster Open Heart Auto is noted for its dressy yet versatile design, featuring striking gradient dials and intricately shaped cutouts that reveal the H-10 movement. It boasts an 80-hour power reserve and Nivachron hairspring. The watch is available in 36mm, 40mm, or 42mm stainless steel cases. On balance, the Hamilton Jazzmaster Open Heart Auto is appreciated for its visually engaging dial and movement display at its price point.

From video reviewers

The smoked dial's precision cutouts offer a captivating view of the automatic movement. Legibility is compromised by the open-heart design.
