You may need to measure the case of a watch when you purchase a new watchband or shop for a new wristwatch. A watch case is the part of the watch that houses the dial, battery, movement, and other internal working parts. A watch case can be any size, so knowing the exact measurements can be very useful as you shop or look for watch accessories. You can use wristwatch case measurements to choose new watchbands or find a men's or women's watch with the right-sized dial for your look and style. Follow these steps to quickly and accurately measure a watch case.
Measuring the watch face can help you visualize how new watchbands will look, and it can also be useful when shopping for an entirely new watch. Measure across from one side of the watch to the other to get the diameter of the watch face. Millimeters are still recommended for an accurate measurement, although other units may be used by some watch retailers.
