Owners + reviewers, side by side

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

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 Arctic Steel Navigator

The Marathon Arctic Steel Navigator is praised for its pragmatic, no-nonsense design and comfortable wearability due to its thinner, ergonomic steel case. Owners and reviewers highlight its highly accurate ETA F06.412 quartz movement, which offers exceptional timekeeping and a seven-year battery life with a field-serviceable battery port. One owner reported their Arctic Steel Navigator's pip fell out shortly after unboxing, and the bezel later became gritty and hard to turn, though another owner found success cleaning their gritty bezel with soap and water. A reviewer noted a preference for a different strap design for a cleaner tail tuck. On balance, owners and reviewers rate the Marathon Arctic Steel Navigator highly for its pragmatic design and accurate, reliable quartz movement.
