What people say

Owners + reviewers, side by side

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

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.

Longines LEGEND DIVER 42

Owners widely praise the Longines Legend Diver 42 for its appealing retro skin-diver aesthetic, excellent legibility, and functional inner bezel, with reviewers noting its strong value proposition below $2,500 and capability in shallow dives. Some owners find the blue dial pops in the sun and appreciate the quickset date. However, several owners report disappointment after seeing the watch in person, finding it underwhelming and lacking dial depth. Specific criticisms include original leather straps peeling easily, a clasp that scratches readily, dust getting on the dial, and lume that is not particularly strong or matching vintage charm. The 50mm lug-to-lug length is noted as potentially overwhelming for smaller wrists, and one owner experienced the minute hand scratching the hour hand. Accuracy figures are not consistently reported across sources.
