Seiko 5 Sports SKX HDB003J 145th Anniversary Edo Purple Limited Edition Japanese Wristwatch

The Seiko 5 Sports SKX HDB003J is the 145th Anniversary limited model in the SKX series — the design platform originally born in 1968 and the most beloved sports watch silhouette in Seiko's modern catalogue. The SKX is a reference point for a generation of watch collectors internationally; its proportions, crown position, anti-rotation bezel, and screw-lock case architecture define what an honest, uncompromising sports watch looks like. This anniversary model takes that platform and renders the Edo Purple theme as a modern colourway that sits naturally alongside the SKX's original casual-sport identity: the purple dial evokes the fashion colours of the Edo period, gold logos and haircutting-finished indices add the anniversary accent, and the three-row stainless steel bracelet gives a sense of premium mass on the wrist without adding unnecessary complication. Caliber 4R36, 41-hour power reserve, day-date window, screw-lock crown. See-through screw caseback with "LIMITED EDITION" marking. World limited to 9,999 pieces with 999 pieces allocated domestically. Releasing October 9, 2026. *Pre-Order! Estimated release and shipment from October 9, 2026.* Key Features: SKX Architecture — Anti-Rotation Bezel, Screw-Lock Crown, 10ATM: The HDB003J is built on the SKX platform's defining physical architecture: the anti-rotation bezel, the 4 o'clock screw-lock crown position, the three-row bracelet, and the curved Hardlex crystal that gives the case its recognisable profile. All the decisions that made the original SKX one of the most trusted sports watches ever produced are retained here, unchanged. Edo Purple Dial — Hairline-Finished Indices, Gold Logo: The deep purple dial references the Edo fashion colours that give the anniversary collection its theme. The haircutting-finish on the top surfaces of the indices creates a catch-light effect that shifts across the dial as the wrist moves. The gold logo and "Automatic" text add the anniversary accent without disrupting the dial's sporting character. Three-Row Stainless Steel Bracelet — Premium Mass & Wrist Presence: The three-row bracelet is the bracelet type historically associated with the SKX's most premium executions — wider centre links flanked by brushed outer links, with a double-lock clasp for security. It sits well on the wrist and gives the watch a substantial, confident presence. Caliber 4R36 — 41hr Power Reserve, Day-Date: 24 jewels, approximately 41 hours power reserve, automatic with hand-winding, hacking seconds. Day and date window at 3 o'clock. See-through screw caseback. 10 bar (100m) water resistance.
