-
With clock. It features a beautiful built in Seiko watch with alarm! Author Enrico Tedeschi suggests in his book 'The Magic of Sony' that the TRW-621 was the first radio with a built in watch. It was probably the first transistor radio with this feature. Sony released another watch radio in 1961/62, the TRW-625 was smaller than the TRW-621 and the watch was built into the center of the speaker grill! In 1962 Matsushita released the National T-98 'Portalarm' which is very similar in appearance to the Sony TRW-621 it also uses a Seiko watch. TRW-621 also features a recessed stand for lounging, a gold metallic face and a textured metal speaker grill. The front half of the cabinet is colored ivory and the back is coral colored. This radio can also be found colored black with a coral back and ivory with a grey back.
