Dream on boys. Panerai are making new sizes to sell more watches. They can't go bigger so they are going smaller.
Every Haute Horologie maker, never mind the standard premium brands like Rolex, are increasingly making bigger watches to hold ever more complex movements and show off cool new materials - carbon, ceramic, etc.. There will always be a great market for the elegant "dress" watch but the average watch from 99% of the makers is gettting bigger. So start doing your wrist curls.
