What people say

Owners + reviewers, side by side

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

Oris Great Barrier Reef Limited Edition IV

The Oris Great Barrier Reef Limited Edition IV's 43.55mm case is surprisingly wearable on a 7-inch wrist due to its new design. Owners report the Oris Great Barrier Reef III, a 45mm watch, is massive and nearly 20mm thick. Overall, owners find the Oris Great Barrier Reef Limited Edition IV wearable despite its size, citing its new design as a key factor.

From video reviewers

The striking turquoise-to-navy gradient dial is a notable feature. The 43.5mm stainless steel case is noted for its ergonomic fit.

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.
