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.

Sugess Seestern Heritage S436-2 BB GMT

Owners widely praise the Sugess Seestern Heritage S436-2 BB GMT for its 39mm sizing, 12mm thinness, and light yet solid feel, with many appreciating its legibility due to the matte dial, clear crystal, and strong lume, though one owner flags the lume as a weak point. The case finishing is considered excellent, and the blue dial and satin finish are favorably compared to alternatives. Some owners report issues with a loose bezel, with others finding it improved after tuning, and one owner notes the seconds hand is too short. The bracelet clasp lacks sufficient micro-adjustment and screw pins are difficult to remove. On balance, owners rate the Sugess Seestern Heritage S436-2 BB GMT highly for its comfortable wearability and attractive finishing at the price.
