Management Number 0517 0509T20-5 385 68 This SEIKO solar radio-controlled watch is powered by the 7B22 movement — a highly capable caliber that combines two of the most practical technologies in modern watchmaking. The solar-powered system converts light into energy, eliminating the need for regular battery replacement. At the same time, the watch automatically receives Japan's standard radio time signal to self-correct both the time and calendar with exceptional precision. The dial is clean and restrained, embodying SEIKO's characteristic honesty in design. Free of unnecessary ornamentation, it brings a polished, professional presence to the wrist — equally at home in a business meeting or a formal occasion. The timeless case silhouette ensures versatility across a broad range of settings, making this a reliable everyday companion built to last.
