This was a commission piece for a brony on the UK of Equestria forums - 1mm aluminium sheet about 25cmx35cm, engraved with a diamond burr, lightly polished and copper details,with a standard quartz clock movement. Turned out better than I first expected, hope the client likes it!
For one like this, £25 including UK delivery or £28 including US delivery - of course, you get to choose the engraved picture, size,shape,metal,details, type of clock hands, etc!
