Fortis Marinemaster M-40vsHamilton Khaki Navy Scuba Automatic GMT 43mm Bronze

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.

The Hamilton Khaki Navy Scuba Automatic GMT 43mm Bronze is widely praised for its excellent fit and finish, pleasing proportions with a 22mm lug width, and a matte dial that minimizes glare. Owners appreciate its 300 meters of water resistance, 80-hour power reserve from the H-14 automatic GMT movement, and the fact that it wears smaller than its 43mm size suggests. Some owners find the flush crown guards and rock-solid feel make it an outstanding beater dive watch. However, opinions are split on the date placement, dial markers, and logo text size, with some preferring a cleaner look and faster setting due to the lack of a date window, while others note the absence of a lumed bezel pip. One owner dislikes the trade-offs for the 80-hour power reserve, preferring a smoother second hand sweep and more torque, and finds the bezel action tight.
