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.

Yema Navygraf Heritage

Owners widely praise the Yema Navygraf Heritage for its comfortable 39mm wearability and faithful 1970s reissue design, noting craftsmanship better than expected. Some owners report quality control issues including bezel free play and misalignment, while others find the bezel very tight to turn despite precise 120 clicks. The in-house MBP2000 movement is noted by some to be loud and run approximately +10 to +15 seconds per day. On balance, owners appreciate the Yema Navygraf Heritage for its retro aesthetic and comfortable sizing, with noted concerns around movement accuracy and bezel action.
