What people say

Owners + reviewers, side by side

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

Glycine Combat Sub Sport

Owners widely praise the Glycine Combat Sub Sport for its exceptional value, thin profile, and solid build quality, often noting its finishing and wearability as superior for its price point. Reviewers consistently flag its slim case, with measurements around 10.4mm to 10.8mm, and appreciate its non-homage design and comfortable lug curvature. Accuracy figures vary, with one owner reporting only 2 seconds per day loss, while another notes their Sellita SW200 movement runs at +6 to +9 seconds per day. Some owners report inconsistent power reserve not reaching the advertised 42 hours and find the lume sub-par for nighttime legibility. A few also mention sharp bracelet edges and a potentially short bracelet for larger wrists, and one owner dislikes the "COMBAT" text on the dial. On balance, owners and reviewers rate the Glycine Combat Sub Sport highly for its impressive thinness and value as a Swiss automatic diver.

Islander Greenport 39mm Dive Watch with Black and White Dial #ISL-300

The Islander Greenport 39mm Dive Watch with Black and White Dial #ISL-300 is praised for its 39mm size and comfortable fit, with its bi-directional dual time bezel noted as a useful feature for tracking different time zones. Owners appreciate the lumed ceramic bezel and the slightly domed sapphire crystal. One owner specifically highlights the dial layout as a strong positive. The screw-down crown is also mentioned as a nice touch. On balance, owners rate the Islander Greenport 39mm Dive Watch with Black and White Dial #ISL-300 highly for its wearability and functional bezel.
