The clock is all metal with a glass face that opens. The face clicks shut and has a small lever to press on the side to open.
The face is just over 6. It has a crack that is about 3 in length and a few scratches underneath. I tried to get an angle in the last pic so you could see.. Hard to do with so much reflection. The gold metal sunbeams (short ones) have some wear and minor discoloration ina few spots.
The key for winding is included and it seems to work fine and keep good time from what I can tell. No wires or batteries needed!
