Islander Calabro GMT World Time Automatic Watch with Anthracite Dial #ISL-316

Islander Calabro GMT World Time Automatic Watch with Anthracite Dial #ISL-316 offers excellent value at $329 MSRP, featuring a handsome anthracite dial with applied indices, a sapphire crystal, and a quality 120-click unidirectional bezel. Owners highlight the NH34 movement and well-proportioned 40x48x20mm case. Overall, owners rate the Islander Calabro GMT World Time Automatic Watch with Anthracite Dial #ISL-316 highly for its value and feature set at the price point.

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.
