Housed in a 42.5 mm stainless steel case, the watch stays true to the classic SKX shape, including the iconic 4 o’clock crown and unidirectional bezel—now upgraded with a glossy Hardlex insert for a refined finish. Powered by Seiko’s reliable 4R36 automatic movement, it offers both manual winding and hacking, plus a day-date complication displayed in both English and Kanji (exclusive to the JDM SBSA309 variant). A black silicone strap ensures comfort and durability, whether on outdoor adventures or daily wear. The see-through case back offers a glimpse into the mechanical movement, while the 100-meter water resistance and anti-magnetic protection round out its everyday practicality. The Daichi Orange isn’t just a bold design—it’s a modern tribute to Seiko’s field and tool-watch heritage.
