Seiko Radio-controlled clock that announces the time by voice Pyramid Talk A voice-announcing clock with a novel design, with no time display on the front of the clock. The DA570G was released in February 1984, and this item is the DA572G, so I believe it is a fairly early model. Operation confirmed. Although I don't know the original sound, the voice seems slightly distorted. Also, I purchased it as a used item, and there is a mark "NST" on the back for some reason, since the time of purchase. *Please note that we cannot offer a discount. *Please also understand that this is a used and old item.
