【Radio-Controlled Watch】SEIKO ALBA ROOX RADIO CONTROLLED Battery replaced, operation confirmed. Receives radio signals properly. This is an early radio-controlled watch from SEIKO ALBA. At the time, SEIKO didn't have the radio-controlled watch technology, so the module is made by Junghans of Germany. The back cover is made of glass to allow radio waves to reach it easily, and the body and belt are made of titanium, making it light. This watch is full of ingenuity. There are signs of use, scratches, and marks, but the condition is not bad for a watch of that era. The wrist size is about 19.3cm.
