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.

Marathon Jeep Rubicon GSAR

The Marathon Jeep Rubicon GSAR is widely praised as a rugged, high-quality tool watch that successfully blends Jeep branding with Marathon's functional heritage, featuring a unique dial with tritium illumination and an automatic Sellita SW200-1 movement. Owners appreciate its satisfying bezel action and durable build, making it a reliable daily wear that pairs well with Jeep's rugged image. However, some find the Jeep logo to be corporate and out of place with Marathon's austere design ethos, while one owner notes that second-hand examples can show wear on the bezel. The watch is priced at $1,500 USD. Overall, owners and reviewers rate the Marathon Jeep Rubicon GSAR highly for its robust construction and distinctive tritium lume, which are considered its strongest assets.
