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-40

Owners praise the Fortis Amber Orange for its gorgeous appearance and strong wrist presence, noting its crazy lume and 70-hour power reserve. The Doxa SUB 300T, described as having a superb, eccentric design with a highly legible dial and functional no-decompression bezel, uses an ETA 2824-2 movement. However, the SUB 300T's 42.5mm case wears large and its 14mm thickness is not ideal for dress shirts, though it boasts 1,200m water resistance. On balance, owners appreciate the Fortis Amber Orange for its striking aesthetics and impressive lume.

Hamilton Khaki Aviation Day Date Auto

Owners and reviewers widely praise the Hamilton Khaki Aviation Day Date Auto for its handsome, legible dial with raised indices and day/date complications, and its versatile, modern pilot watch design. The fully brushed case and good lume are noted strengths, with one owner finding it wears comfortably on a NATO strap. The H-10 caliber offers an 80-hour power reserve, though its decoration and regulation are less refined. Some find the 42mm size large and the skeletonized hour hand tip visually unappealing, while others note the AR coating is decent but not exceptional. Overall, owners and reviewers rate the Hamilton Khaki Aviation Day Date Auto highly for its practical design and value at its price point.
