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.

DOXA SUB 300T

Owners widely praise the DOXA SUB 300T's functional and distinctive design, with reviewers highlighting its historical visibility and robust build. Legibility is consistently noted as excellent, with reviewers appreciating the functional no-decompression bezel and distinct hand shapes. The watch's accuracy is reported as good, with one owner seeing a 3-4 second daily gain, though the 38-hour power reserve is considered underwhelming by some at its price point. Criticisms include a stamped clasp that feels out of place and a bezel that may have lateral movement. The 42.5mm case is described as substantial and heavy, appearing larger due to extra width and making it unsuitable for dress shirts, a trade-off for its 1200-meter water resistance. On balance, owners and reviewers rate the DOXA SUB 300T highly for its unique design and robust dive watch capabilities.
