I've had a second gen Seiko Orange Monster back when I first was collecting. But I also have an Orange Samurai that I am looking to mod the bezel, just haven't found the right combo I want just yet.
But to answer your question, I wear this usually with a blue shirt or something that can compliment the color. Do I wear it sparingly? No not really, orange normally can stand on it's own, like a yellow dialed watch. The key is to compliment the colors, you can always do the halloween orange and black as well, but I've came to realize, grey and orange work very well together, almost like the stainless steel bezel.
