These high quality chapter rings are made of ABS plastic, and painted to precision. When modding (customizing) your favorite Seiko watch, sometimes just changing the hands isn't enough. That's where a subtle change of color of the chapter ring can go a long way in enhancing the overall look and uniqueness in it's appearance. Whether you're putting together that one-of-a-kind mod. Or just oh-so subtly want to give your existing stock an accent with that subtly "something extra". Then these chapter rings are for you. Just press them into the recess in the case for drop down installation.
