The sole truly "timeless" bit of jewelry is the watch. From the pocket watches of yesterday to the wristwatches of today, timepieces have been utilized by men and women across the globe for generations. Luxury watches from Switzerland and Italy have always been the most sought-after timepieces. They're crafted from the best materials imaginable: gold, genuine leather, stainless, and so forth. Some have diamonds and other precious gems as accents.
