These models were designed to offer reliable automatic winding and refined aesthetics for everyday wear. The inclusion of the caliber 7606A brought practical innovations to the series, notably the dedicated 3 o'clock pusher for quick-setting the date, while the 4 o'clock hidden crown emphasized the convenience of the automatic winding system. This era of Seiko production is celebrated for establishing the robust mechanical foundations and clean design language that continue to define the brand's heritage. / Second Vintage SKU: SEI-SDX-0012
