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.

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.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePurple Crystal Glass Crown — Visible from the Side\u003c\/strong\u003e: 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.
