SEIKO Digital Wall Radio Controlled Clock - Calendar, Hygrometer, Thermometer, May 2005

The back with the openings for the sensors and the setting buttons

Only Kanji on the watch back
indicates that this was a watch targeted at the Japanese domestic market or the countries that read Kanji (Chinese script). In Thailand the watches were obviously not the big hit, since they were reduced and for sale.
4 openings in each corner for the sensors (temperature/humidity). 3 setting buttons labeled in Kanji again, but really easy to set the clock without manual. Behind the display stand, the Made in C.... visible. Can you guess where the watches were made? :)
