Model No is QQZ472S and I can't find which battery I have to use in it...I looked, even on Seikosha site. It's a mantle or table clock, brushed and chrome steel, another number on it is a Cal #21201A...some letters under the dial/battery case are #SCCZ....anyone know?

Hi, I had the same problem buying a used one...but I matched up the slot in the drug store and it is working on an Energizer A76!

I am also looking for information on my gold/acrylic Seiko desk clock - circa 1980's. It's labeled QZ 123G, Cal.21102. It's in excellent condition and works well; I'm curious about why I can't find any evidence of the model anywhere. It's a modern design - arched gold (about 7 inches tall)with a gold base and an acrylic body in which the round gold clock is suspended. Twelve gold "bullets" suspended in the acrylic represent the numbers. Anybody know anything about it?
