Today’s trends in sports watches are bigger is better.Once watches were the diameter of a quarter, now watch diameters have reached as much as the U-Boat U-1942, 64.4 millimeters.Many men want a watch that will keep good time as well say something about their status and style.The larger the watch, the more attention it is more likely to draw.

The introduction of Panerai an Italian watch manufacturer to the American market about a decade ago pushed the trend of the larger watch sizes.Other watch manufacturers followed Panerai’s lead including IWC, Hublot and Rolex.
