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.
