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 Marine Nationale Quartz

Owners praise the Yema Navygraf Marine Nationale Quartz for its well-made case, clean legible dial, and comfortable 39mm size, with one noting its thin profile for 300m water resistance. Accuracy figures vary, with one owner reporting +6 seconds per day and another seeing it keep within COSC time. Minor criticisms include a steel bracelet with a slight rattle and sharp edges, bent bracelet pins, and in one instance, crooked dial printing. On balance, owners find the Yema Navygraf Marine Nationale Quartz offers good value and wearability, with its French design and thinner case being key highlights.
