This unique old fashioned styled pocket watch features a green cabochon at the center surrounded by emerald colored Swarovski crystals. The clock face is revealed by pushing a button at the top. There is also a mechanism, located at the top, that you can use to adjust the time. A battery IS included in the watch so there is no need to purchase one separately. The pocket watch measures 2-1/2" tall and 2" wide and it will come on a bronze chain in the length of your choice. Tip: If you are unsure what necklace length you need, then you should use a piece of string or ribbon to measure your necklace length. Hold the string in a loop around your neck, and pull it down until it hangs where you would want a necklace to hang and then measure the string's length using a ruler or tape measure. Your treasure will promptly ship from the United States and in a free complimentary gift box!
