This watch is very weighty and thick. It fits under a long sleeve shirt but just barely. I have large wrists and like the fact that it is very proportionate to my arm. I have banged it a few times and there is not the tiniest mark on it. The strap is string enough to cinch the watch to your wrist and eliminate play yet not be uncomfortable. I still cannot get over the height of the watch. This is my first Lum-Tec and I am impressed. I already own Rolex, Breitling, Panerai, Luminox, and others.
