This is a limited edition SWATCH 100 Million Commemorative Model. This item has been stored with the battery removed since purchase. A new battery was installed in October 2015, and the watch is currently working correctly. The battery used is Renata 390 SR1130SW. The case and instruction manual are included, but the case hinge is cracked due to damage when opening. Please check the images and consider purchasing. As this is an old item, those in good condition are becoming rare. If you are looking for one, please consider purchasing it as soon as possible.
