The Lum-Tec 500M2 Dive Watch is a bruiser. Wider than 45 mm and thicker by 17 mm, good thing it came with a rubber strap instead of a bracelet. Otherwise, the weight would be too obvious. This is a simple watch with no other complications except for the 3 time-hands. PVD with a very simple uni-directional bezel. The lume is exceptional (this is the call-to-fame for Lum-Tec). The dome on the crystal is a beauty. Despite its size and weight, it is easy to wear on the wrist and comfortable. This can be attributed the the properly designed rubber strap.
