This polished gold plated pocket watch for men features a unique open face design with a calendar dial that allows you to see the inner mechanical workings of the watch. The white calendar dial has black roman numerals and striking blue dials. This pocket watch uses mechanical, or wind up, movement so it doesn't need batteries but will need to be wound daily. The back has a see through viewing window as well. This time piece comes with a matching 12 inch chain and is packaged in a gift box.
