Our square-hinged wood box with a black piano finish opens to reveal a round clock face with silver trim and quartz movement. Inside the lid, there is also a round brushed silver 2.25" diameter engraving plate that is included. The engraving plate sits in a pre-cut recess. Once you add your engraving, the adhesive back is peeled off the engraving plate and it just sticks into place. The overall dimensions of the box are 2.875" x 2.875" x 1.5". Includes four small, round foam feet to help prevent scratching. The battery is a standard watch battery and is included.
