Some cities never sleep, and Tokyo is one of them. When the sun slips behind the skyscrapers, the Japanese capital reveals another face, that of a metropolis lit by millions of points of light. This singular atmosphere is what King Seiko set out to capture in its new VANAC Cosmic Tokyo: a nocturnal, almost celestial take on a collection whose comeback never stops surprising us.

VANAC, a story still being written
Some watch collections cross the decades without really showing their age. Others disappear and then return, sometimes much later, with a renewed personality. The King Seiko VANAC belongs to the second category.
Born in 1972, at a time when Japanese watchmaking dared every aesthetic audacity, it already stood out for its angular cases, expressive dials and particularly bold colours. This was a watch that had no wish to blend into the horological landscape, preferring instead to impose its own vision of time. More than half a century after its birth, the VANAC returned to the spotlight in 2025.
At the time, Passion Horlogère devoted a first article to the rebirth of this collection, highlighting Seiko’s ability to draw on its heritage without merely reproducing the past. Since then, the family has grown with new interpretations, notably titanium versions, along with a commemorative edition marking the Japanese company’s 145th anniversary. With each new creation, the same philosophy holds: strong architecture, serious mechanics and an instantly recognisable identity.
With the VANAC Cosmic Tokyo, King Seiko now lets light do the talking. Or rather, the light that appears when night falls.
Tokyo, a city that becomes a dial
The inspiration behind this new creation is no accident. Since its rebirth, the VANAC collection has maintained a special relationship with Tokyo, the historic cradle of King Seiko. Its first contemporary versions explored the different tones of the Japanese sky: the violet of dusk, the deep blue of night and the silvery shades of sunrise. The Cosmic Tokyo continues this exploration, but shifts the gaze.
It is no longer simply a matter of contemplating the horizon. Now we must picture the city after dark, when avenues, buildings and thousands of lit windows draw an artificial constellation as far as the eye can see. To convey this atmosphere, Seiko has created a dark dial scattered with fine sparkling particles. The result is particularly interesting: depending on the angle of the light, these tiny glints seem to appear and then vanish, evoking the countless points of light of a metropolis seen from above.
The effect is not meant to be a constant, ostentatious shine. Instead, it relies on subtlety, variation and depth. The hands and the ring carrying the indexes also take on dark tones, as if to better let the dial express this particular luminosity. The contrast between the restraint of the whole and the sparkle of its surface gives this VANAC a new personality: a certain urban poetry, in short, in a watch whose design nonetheless remains resolutely architectural.
An architecture sculpted in steel
While the Cosmic Tokyo changes the expression of its dial, it retains the aesthetic fundamentals that define the contemporary VANAC. Its 41 mm stainless steel case is full of facets and sharp angles. Its mirror-polished surfaces catch the light, while the taut lines of the case band give it that characteristic look of having been sculpted from a block of metal.
The absence of a traditional bezel accentuates the presence of the dial and contributes to this instantly identifiable silhouette. The metal bracelet naturally extends the lines of the case. It alternates polished and brushed surfaces, creating an interplay of reflections that directly answers that of the dial. This continuity between case and bracelet places the VANAC in the world of sport-chic watches with strong personalities, without erasing its historical roots.
Enthusiasts will also recognise two small details that have become emblematic: the 12 o’clock index and the counterweight of the seconds hand both take a “V” shape, a discreet yet essential signature of the collection. At 14.3 mm thick, this King Seiko has a definite presence on the wrist. Its proportions reflect a deliberate aesthetic choice rather than an absolute quest for thinness.
A box-shaped sapphire crystal, with anti-reflective treatment on its inner surface, protects the dial. The hands and indexes carry LumiBrite luminous material, while a screw-down crown and a screw-down caseback contribute to a stated water resistance of 10 bar. Enough to consider everyday wear without sacrificing the character of this creation.
The 8L45 calibre, mechanics to match the ambitions
Behind this assertive aesthetic personality lies a movement that deserves our full attention. The VANAC Cosmic Tokyo is powered by the Seiko 8L45 automatic calibre, a high-end movement developed to meet the demands of contemporary mechanical sports watches. Beating at 28,800 vibrations per hour, or 4 Hz, this calibre has 35 jewels and a power reserve of around 72 hours. Three days of autonomy means you can take your watch off on Friday evening and find it still running on Monday morning.
Seiko states an accuracy of between -5 and +10 seconds per day, an interesting performance for a mechanical movement also designed to favour robustness and reliability. The automatic winding can be supplemented by hand, while the hacking seconds function allows precise time setting. The transparent caseback, for its part, offers the chance to observe this movement and appreciate its mechanical construction.
The appeal of this movement nevertheless goes beyond its technical specifications alone. By fitting the VANAC with the 8L45 calibre, Seiko confirms its intention to make this collection a demanding watchmaking proposition, in which original design is not the only argument. The VANAC is not simply a watch with character. It also intends to be a truly fine mechanical watch.
A new personality in the VANAC family
In many respects, this Cosmic Tokyo is a logical evolution of the collection. After the first colourful versions and the titanium models, Seiko offers here a more mysterious, more nocturnal interpretation, perhaps also a more discreet one at first glance. The creativity lies not in a radical transformation of the case, but in a new way of working with contrast and the perception of light.
That is precisely what makes this proposition interesting. Where some VANAC models immediately proclaim their originality through bold hues or very pronounced geometric effects, the Cosmic Tokyo seems to prefer a form of restraint. It will of course be necessary to see the watch in real conditions to fully appreciate the variations of its dial. Photographs convey the intention, but this type of finish generally takes on another dimension as the light shifts on the wrist.
Offered at a recommended retail price of €3,400, this new HKF005J1 reference has been available in Seiko boutiques and through authorised retailers since October 2026. It therefore sits below the titanium versions presented earlier, without giving up the 8L45 calibre or most of the collection’s technical features.
When watchmaking tells more than the time
What ultimately appeals in this new King Seiko VANAC Cosmic Tokyo is its ability to tell a story without giving up its watchmaking identity. The urban inspiration is not artificially stuck onto an existing watch. It extends an aesthetic approach begun with the collection’s rebirth, built on the idea of translating the landscapes, colours and energy of Tokyo into a mechanical object. This approach echoes the most interesting thing watchmaking has to offer: the meeting of technical know-how, heritage and emotion.
The VANAC Cosmic Tokyo does not revolutionise the measurement of time, and it does not claim to. It simply reminds us that a watch dial can be much more than a reading instrument. It can also become a landscape, an atmosphere, an invitation to travel. And when Tokyo lights up at nightfall, all you need to do now is glance at your wrist to catch a few of its sparkles.
