King Seiko’s VANAC has always been the louder sibling in the family, the one with sharper angles, stronger colours and a taste for 1970s futurism.
The latest additions don’t dilute that character, but they do make the watch easier to live with thanks to three new titanium references and a separate 145th anniversary limited edition in Seiko Blue.
It’s a smart move for a design that trades heavily on geometry and wrist presence.
At a glance
- King Seiko has introduced three regular-production VANAC models in titanium alongside a stainless steel 145th anniversary limited edition.
- The titanium references retain the 41mm faceted case, integrated-style bracelet and Caliber 8L45, while cutting 64g from the steel version.
- Prices are SGD 5,450 for the titanium models and SGD 4,632.50 for the 800-piece anniversary edition.
The VANAC gets a lighter metal without losing its edge
The new titanium VANAC references HKF001, HKF002 and HKF003 keep the proportions of the revived model, measuring 41mm across, 14.3mm thick and 45.1mm from lug to lug.
Those numbers still put the watch firmly in sporty territory, but the relatively contained lug-to-lug length helps keep the case from sprawling across the wrist.
The bigger change is material.
Seiko has moved these three references into grade 5 titanium, dropping the weight by 64g compared with the stainless steel models and bringing the total to around 128g.
That matters on a watch like the VANAC, where the case and bracelet are part of the visual architecture rather than quiet supporting parts.
The bezel-less case has broad planes, angular shoulders and polished facets, while the bracelet runs directly into the case to create an integrated-style profile.
It isn’t a fully integrated bracelet in the strictest sense, as the quick-release spring bars allow it to be removed, but the look is very much in that family.
Titanium’s darker tone also plays well with the design, giving the polished and brushed surfaces more contrast than a flatter reading in steel.
Tokyo highway energy on the new dials
The dial treatment is where the titanium VANAC models make their most visible departure.
Instead of relying only on horizontal striping, the new dials add a radial pattern that moves outward from the centre, giving the surface more motion under light.
The three colours are purple for HKF001, grey for HKF002 and black for HKF003.
Seiko links the look to the sensation of moving along Tokyo highways toward the city skyline, which fits the VANAC’s long-standing relationship with urban futurism.
The details remain familiar, including luminous hour and minute hands, LumiBrite hour markers, a framed date window at three o’clock and the recurring V motif at 12 o’clock and on the seconds-hand counterweight.
The purple HKF001 has already gained extra attention after being selected by the GPHG Academy for the 2026 Challenge category.
For a watch line born in 1972, that kind of contemporary recognition feels especially well placed.
Seiko Blue marks 145 years
The fourth model, HKF004, takes a different route.
Rather than titanium, it uses the stainless steel VANAC case and pairs it with a silver-white dial carrying horizontal striping, a vivid blue index ring and blue hands.
That shade is tied to Seiko Blue, a colour the brand traces back to the 1960s and has used as a connecting theme for its 145th anniversary watches.
The anniversary marks 145 years since Kintaro Hattori opened the business in 1881 that would become Seiko.
Turn the watch over and the sapphire display back shows a blue King Seiko shield, along with Limited Edition engraving and an individual number.
Production is capped at 800 pieces.
Caliber 8L45 keeps the VANAC in serious sports-watch territory
All four models run on Seiko’s automatic Caliber 8L45, the movement introduced with the recent VANAC revival.
It offers a 72-hour power reserve and an accuracy rating of +10 to -5 seconds per day.
The movement is visible through the sapphire caseback, with wave-pattern finishing across the rotor and bridges.
A sapphire crystal, screw-down crown and 10 bar water resistance round out the specification, giving the VANAC a practical foundation beneath its more expressive styling.

The titanium models make the VANAC more wearable without sanding down its personality, while the blue anniversary edition gives collectors a cleaner, more commemorative take on the same angular platform.
For anyone drawn to Seiko’s bolder side, this is King Seiko leaning into exactly what makes the VANAC distinct.
