Description
King Seiko brings its boldest 1970s design back in a full titanium execution. The Vanac Titanium trio — references HKF001, HKF002 and HKF003 — pairs the collection's faceted, light-catching dials with a lightweight, bezel-less 41mm titanium case, and puts a Grand Seiko-derived automatic movement behind the caseback for well under US$4,000.
These are continuous-production models rather than limited editions, aimed at the buyer who wants serious in-house Japanese watchmaking without stepping up to Grand Seiko pricing. HKF001 arrives in purple, HKF002 in silver-grey and HKF003 in black, each priced at EUR 3,950 / US$3,850 and available from July 2026.
Design
The Vanac's identity has always been its geometry, and titanium suits it. The 41mm case is bezel-less, 14.3mm thick, and finished with the sharp brushed-and-polished contrasts King Seiko is known for. A box-shaped sapphire crystal with anti-reflective coating on its inner surface sits over multi-faceted dials that throw light in every direction — purple, grey or black depending on reference. A screw-down crown and an exhibition caseback round out a package rated to 100m (10 bar).

What's Exciting
The headline is the Calibre 8L45. It is built on the same architecture as Grand Seiko's 9S65 — effectively Grand Seiko movement engineering, without the Grand Seiko finishing tax — and it brings a 72-hour power reserve, a big jump over the old 8L35. Getting that calibre inside lightweight titanium, in a non-limited watch under US$4,000, is one of the strongest value stories King Seiko has told. The Vanac's flamboyant faceted case is a love-it-or-leave-it design, but on the wrist in brushed titanium it reads far more modern than its 1970s roots suggest.
History
Vanac was King Seiko's assertive, design-forward line in the early 1970s, all faceted crystals, coloured dials and angular cases — a product of the era when Japanese watchmaking was flexing hard against its Swiss rivals. King Seiko itself was revived as a standalone collection in 2022, and the Vanac name returned soon after as its most expressive branch. This titanium trio extends that revival with the material and the movement the original could only have dreamed of.
