Hamilton Khaki Navy Scuba Automatic GMT 43mm BronzevsSeiko Prospex Sea 1968 Heritage Diver's GMT Watch Limited Edition

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.

The Seiko Prospex Sea 1968 Heritage Diver's GMT Watch Limited Edition is widely praised for its excellent quality and finishing relative to its price point, featuring a beautiful case, bracelet, and strong Lumibrite lume. Enthusiasts and reviewers highlight the comfortable 42mm case size and the distinctive 4 o'clock crown position. The watch is powered by the in-house 6R54 automatic movement, offering a 72-hour power reserve and rated accuracy of -5/+10 seconds per day, though one source notes the GMT function is secondary. Some find the 4:30 date window divisive, and the bezel clicks are described as quieter than expected. On balance, owners and reviewers rate the Seiko Prospex Sea 1968 Heritage Diver's GMT Watch Limited Edition highly for its refined design and strong value proposition.
