This 18K rose gold dress watch is equipped with the 9SA4, marking the brand's reintroduction of a hand-wound 36,000 vph mechanical movement after more than 50 years.
Today, the ritual of winding a watch has become one of life's pleasures. The simple act of turning the crown engages the senses and forges a deeper connection with the natural flow of time. In the 1960s and 70s, hand-wound 10-beat Grand Seiko timepieces were introduced in pursuit of improved chronometric performance and higher precision. Making its debut in the Evolution 9 series, the 9SA4 represents the first hand-wound dress watch in the new lineup, embodying the continuation of the Grand Seiko style that traces back to the iconic 44GS of 1967. It further refines the allure and elegance of a hand-wound dress watch, with every aspect of the design reexamined: from prominent grooved indices to multi-faceted lugs and a low center of gravity to ensure the renowned comfort and stability of Evolution 9 pieces. The case is crafted from 18K rose gold. The dial features a pattern reminiscent of beautiful birch trees, with an SD mark at 6 o'clock indicating the use of 18K rose gold for the hour markers. With a new layout of the gear train and redesigned components, the movement achieves higher winding efficiency, offering an 80-hour power reserve for the 9SA4, with a 15% reduction in the number of crown rotations required compared to the 9SA5.
