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.

Lum-Tec Solar Marine

Lum-Tec Solar Marine owners praise its all-black diver design, excellent lume, and rugged, tank-like build. One owner finds it a perfect fit for a 7-inch wrist and the most frequently worn watch despite its smaller size. However, one owner cautions that the PVD coating will wear and chip within a year, impacting its appearance, and another finds the price high for a solar quartz watch with added lume. On balance, owners rate the Lum-Tec Solar Marine highly for its robust design and excellent lume, despite concerns about PVD durability and value proposition.
