A date display is positioned at 3 o'clock. The watch is running at the time of listing. Historical & Collector Value SEIKO has a long history of developing practical quartz, solar, and radio-controlled wristwatch technology. Radio-controlled solar models combine light-powered operation with automatic time correction when a compatible radio signal can be received. Reference 7B52-0AG0 represents this practical side of SEIKO's watchmaking in a more traditional dress-watch format. Its restrained case size, gold-tone accents, leather strap, and analog display make it an attractive choice for collectors and users who appreciate Japanese technology presented in a classic design.
