For a time during the late 80s/ early 90s I tried using a pocket watch but I kept forgetting to take them out of my pocket before laundering. When I saw this had a belt pouch I decided to try this along with another watch or two that could be worn on the belt. I never actually got around to using this and eventually the battery ran out so while new it will need a new battery. I now either use my cell phone like everybody else or a wristwatch because my activities no longer entail dunking my hands in water up to my elbows. The watch face is 1.5 inches in diameter.
