One of the crucial pieces of information that many people look for when considering a watch is the width/diameter of the case, a number usually expressed in millimeters. This is a measurement that is important to many watch buyers, who in evaluating the suitability of one for purchase, has to get a sense of whether it is too big or too small, a concern especially significant for those who’s wrist size resides at the upper or lower limit of possibility.
With the wide range of offerings in case widths as well, one also establishes, by way of experience, a range within which a probable acceptable fit might occur. The importance of this is obvious; too small, and the watch has barely any presence, too big, and one runs the risk of looking like one is wearing a clock on the wrist.
Not helping the situation as well is the trend over the past decade or so of case sizes going up, often testing the limits of sanity at each new mark. Years ago, before the trend of large watches took hold, 36mm, the typical size of a men’s Rolex for decades, was considered large.
