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.

Yema Superman Worldtime GMT

Owners widely praise the Yema Superman Worldtime GMT for its premium feel, unique bezel-lock mechanism, and attractive domed crystal. Some owners note the aluminum bezel insert is less desirable than ceramic and report the bracelet clasp can be stiff or difficult to open. Inconsistent quality control and poor customer service have been flagged by some owners. On balance, owners value the Yema Superman Worldtime GMT for its distinctive features and comfortable wearability.

From video reviewers

The "Coke" bezel and maxi dial are attractive design elements. The in-house automatic GMT movement is a French alternative to pricier GMTs.
