Have you ever thought about what the right watch case size is for you? Have you checked how big your wrist size actually is? In order to get the correct sized watch, you'll want to check out how big your wrist is first. Some people like to wear bigger timepieces, whereas others like to have smaller options. If you have smaller wrists or like an understated style, you might be uncomfortable in a massive watch size. But a small and delicate dress watch might not suit someone with large wrists or a flashy style. You'll also want to take into consideration of these other key factors when choosing you watch case size: case diamater, case thickness, band width and the design of the watch. Keep in mind of where you plan to wear the watch as well!
