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.

Gavox Watches Longitude

Owners widely praise the Gavox Watches Gavox Longitude Diamond for its 39mm size, integrated bracelet, and amazing finishing, with the wavy blue dial and Kolsterised case being particular highlights. Reviewers and owners alike note the Miyota 9075 GMT movement as a well-regarded engine for the watch. Some owners find the 12.8mm thickness and 43mm lug-to-lug distance make the Gavox Longitude Diamond wear tall, and the quick-release spring bars on the bracelet can be difficult to grip. Overall, owners and reviewers consider the Gavox Watches Gavox Longitude Diamond an eye-catching GMT offering tremendous value at its $900 price point, largely due to its distinctive design and finishing.
