This distinctive pocket watch has been beautifully crafted with the look of yesteryear. The front of the engraved square case houses the obverse of a genuine U.S. coin. The 2005 bison nickels were minted for one year only as part of the Westward Journey series of nickels commemorating Lewis & Clark's expedition. Open the watch, and the coins beautiful reverse design is visible inside the front cover. The face of the watch adds to its look of antiquity, but its quality quartz movement is strictly state-of-the-art. Includes a one-year warranty along with a Certificate of Authenticity.
