So this guide is merely a starter to help the beginning watch buyer understand the range of brands available. Rolex is covered in more detail here, because they are the single brand that has the broadest public perception of excellence. They have become the yardstick by which most watch layman discussions of the high end watch brands go by.
Any mentions of specific brands in particular categories is intended as a general guide to get you started looking, but is in no way a definitive guide to all these brands have to offer. Beyond that, you will have to do more detailed research on the specific attributes of the watch and watch companies you find of interest to determine which are better for your specific wants and needs.
