What people say

Owners + reviewers, side by side

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

Hamilton Khaki Navy Scuba Automatic GMT 43mm Bronze

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.

Sternglas Naos Pro GMT Automatik

Owners report the Sternglas Naos can feel underwhelming with a cheap feel and hands resembling office printer output, with some finding it wears smaller than expected and looks like a toy, though others appreciate its understated design. Reviewers highlight the Argo Automatic variant as a compelling sub-€400 mechanical watch with a colorful dial and practical date wheel, suitable for new collectors, featuring a 38mm case and a Miyota 8215 movement. On balance, the consensus is that the Sternglas Naos offers a mixed ownership experience, with its value proposition and entry-level appeal being its strongest points for some.

From video reviewers

The Sternglas Naos Pro GMT Automatik features a clean Bauhaus design that sets it apart from other GMT watches. A notable weakness is the watch's bezel action, which is not as smooth as some reviewers would have liked. Reviewers disagree on the watch's case size, with one reviewer stating it's slightly larger than the original Naos Automatic, while another reviewer doesn't mention this aspect at all.
