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.

Boldr Rally

Owners widely praise the Boldr Rally's compact 38mm titanium case and excellent value under A$500. The VK64 mecaquartz movement has proven reliable for years, and the sapphire crystal is a welcome feature. Some owners find the dial busy and difficult to read, particularly the black hands against the black subdial, and note the bead-blasted titanium case can be a scratch magnet. The default straps have been described as boring or not holding up to daily wear. Overall, owners rate the Boldr Rally highly for its robust titanium construction and excellent value, despite some legibility concerns.

From video reviewers

The 38mm titanium case with a 44mm lug-to-lug measurement provides a comfortable and compact fit. The 200m water resistance is noted as robust for a chronograph. The 14mm thickness was mentioned as potentially substantial for the watch's size.
