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.

Phoibos Reef Master

Owners widely praise the Phoibos Reef Master for its exceptional value, highlighting its sapphire crystal, DLC coating, and extensive BGW9 lume. The watch is noted for its cool lume, with one owner finding it not bulky despite its robust build. The Shamrock Green dial and texture are highly praised, as is the comfortable bracelet with solid end links. However, the bezel action is described as rough, and the basic folding clasp is a disappointment. Accuracy is reported as excellent, with one owner seeing +-2 sec/day. Some find the 42mm size almost too big for their wrists, and the date window is considered too small. Overall, owners rate the Phoibos Reef Master highly for its impressive feature set and value at its price point.
