Seiko Lukia Grow HEE004J 145th Anniversary Edo Purple Lab Diamond Limited Edition Japanese Women's Wristwatch

The Seiko Lukia Grow HEE004J is the 145th Anniversary limited model in the Lukia Grow series — the Lukia sub-line dedicated to the idea of women who grow and evolve alongside the people who share their lives. Since its launch in 1995, Seiko Lukia has remained one of the most consistently respected women's watch lines in Japan, combining refined aesthetics with serious technical specification. For this 145th anniversary model, the dial wears Edo Purple in a deep, composed tone that carries both gravity and elegance — 11 lab-grown diamonds set at the hour indices (excluding 12 o'clock) cast their reflections across the purple surface throughout the day. The crown is set with a purple crystal glass that is visible from the side of the case — a detail that frames the case's profile rather than disappearing into it. The gold seconds hand and gold Seiko logo reference the anniversary collection's gold accent theme. The case is pure titanium finished with Platinum Dia-Shield — Seiko's most precious surface treatment, which adds platinum to the Dia-Shield compound for a brighter, whiter, more refined finish. At 27.9mm x 8.7mm with curved sapphire crystal and Super Clear coating, this is a genuinely slim and precisely sized piece for a smaller wrist. Japan domestic limited to 400 pieces. Releasing October 9, 2026. *Pre-Order! Estimated release and shipment from October 9, 2026.* Key Features: 11 Lab-Grown Diamonds — Edo Purple Dial: Eleven lab-grown diamonds are set at the hour indices across the dial (excluding 12 o'clock), catching and scattering light across the deep purple surface throughout the day. Lab-grown diamonds are chemically, physically and optically identical to mined diamonds — the choice here reflects Seiko's sustainable material principles without compromising on visual quality. Purple Crystal Glass Crown — Visible from the Side: The crown is set with a purple crystal glass that is intentionally visible from the side profile of the case — a detail that elevates the watch's appearance when viewed at any angle, not only face-on. A refinement level typically associated with high jewellery rather than sport-capable everyday watches. Platinum Dia-Shield — Pure Titanium Case: The case is machined from pure titanium and finished with Platinum Dia-Shield — Seiko's platinum-enhanced version of the Dia-Shield surface treatment, which adds brightness and a finer, whiter character to the finish compared to standard Dia-Shield. Nickel allergy resistant, lightweight, and exceptionally scratch-resistant.
