The Invicta Subaqua Noma IV is a watch of style. Its large 50mm bezel means business. There are a lot of great detail to this watch from the rotating bezel which has screw type markers at the 0, 15, 30 and 45 min markers to the green accents under the chrono faces. What makes this watch unique is the attention to the functional details like a screw down knobs to adjust the time and date. There are also luminous dots that indicate the hours when it is dark. The chrono function works very well. The only downside is the weight. This watch is truly heavy. But then again that's what gives its style.
