Editorial Review Desperado "Linden" Wind Up Mechanical Pocket Watch This beauty features a skeletonized movement with windows on the front and back of the case, and also on the inside diameter of the dial, exposing the intricate workings. The large case is close to the size of the antique "16s" size pocket watches from Elgin, Hamilton, Illinois and Waltham. This high quality mechanical pocket watch features a shock protected 17 jewel wind up mechanical movement. Like all mechanical pocket watches, it must be wound daily to keep time. Unlike a quartz watch, a mechanical pocket watch never needs a battery!
