Ginga Tūrubi 銀河
GINGA - A Landmark First.
For more than two centuries, the tourbillon has represented one of watchmaking’s most celebrated mechanical achievements. It is often viewed as the pinnacle of technical craftsmanship, but that was neverthe reason for creating one.
The question was never whether Hitori could create a tourbillon. It was whether we could create one that still felt unmistakably like a Hitori.
The answer became the Ginga Tūrubi, or “Galaxy Tourbillon”. Rather than using the complication as the centrepiece, the watch treats it as one element within a complete design. The integrated architecture, sculptural case and restrained proportions carry equal importance, resulting in a watch where engineering and design exist in quiet balance.
Japanese Armour, Reimagined
While the Ginga Tūrubi marks Hitori’s first exploration into the world of tourbillons, it remains grounded in the same principles that have shaped every collection before it. Rather than allowing the movement to dictate the watch, Hitori began with the architecture itself.
The case and bracelet were conceived as a single composition, defined by sharp geometry, restrained proportions and a low profile that sits naturally on the wrist. Its inspiration comes loosely from yoroi, the layered armour once worn by samurai, translated into a modern form through overlapping planes and faceted surfaces instead of decorative motifs. There are also subtle echoes of the integrated sports watches that emerged from Japan during the late 1960s and 1970s, though the Ginga Tūrubi is less a revival than an interpretation. It is neither an extension of the Nexus nor a glimpse of every Hitori to come. Instead, it represents a moment of exploration.
Crafted from 316L stainless steel, its proportions were chosen to balance presence with everyday wearability. The integrated bracelet flows directly from the mid-case, creating a continuous silhouette that emphasises the architecture rather than individual components. More importantly, the watch was never designed to impress through specifications alone, but through the coherence of its design.
Viewed closely, the case reveals a disciplined approach to surface treatment. Its only pronounced curve runs along the case band, gradually transitioning into sharply faceted lugs before disappearing into the bracelet. The geometry remains crisp without becoming aggressive, giving the watch a distinct identity from every angle.
Much of the exterior is finished with fine satin brushing, allowing the architecture to define the watch rather than reflections. Mirror polishing is reserved only for the narrow bevels, creating subtle shifts in light that reveal the complexity of the case as it moves. Every surface passes through Hitori’s seven-stage hand-finishing process, carried out by experienced craftsmen in Japan. The diamond-cut crown sits neatly within the profile of the case, preserving both comfort and the uninterrupted flow of the design.
Taken as a whole, the Ginga Tūrubi is more than a case designed to house a tourbillon. It is an exploration of proportion, geometry and craftsmanship, demonstrating that mechanical complexity need not come at the expense of restraint. Like every Hitori before it, the watch was shaped by a simple question that guided the project from the beginning:

Form, Texture, and Architectural Light
“The dial doesn’t simply tell the time. It invites you to pause. The longer you look, the more it reveals. Layers begin to emerge, reflections shift, and familiar details take on a different character. It is a quiet kind of beauty, one that rewards curiosity rather than demanding attention.” — Hitori
The Ginga Tūrubi continues Hitori’s restrained approach to watchmaking, where every element is considered, purposeful, and free from excess. At first glance, its proportions feel familiar. The case remains clean andbalanced, framed by a flat sapphire crystal with an inner anti-reflective coating that allows the eye to settle naturally on the dial beneath. Like many Hitori watches before it, the true character of the piece begins with its surface.
Drawing inspiration from the tranquil canals of Yanagawa in Fukuoka, the dial captures the gentle movement of water flowing beneath willow trees and weathered stone bridges. Fine undulating textures ripple across its surface, creating subtle variations in light that never overwhelm the eye. Rather than relying on dramatic finishes, the dial invites quiet observation, revealing new details as the day unfolds.
Encircling the dial is a chapter ring finished in Hitori’s signature satin treatment. Individually applied star-shaped hour markers introduce a subtle nod to mid-century references such as the Rolex Reference 6088 “Galaxy”, while remaining unmistakably modern in execution. Alternating with elegant Art Deco numerals at the cardinal positions, the composition balances nostalgia with restraint, never feeling overly referential.
The faceted Sashi Yari hands continue this dialogue between tradition and contemporary craftsmanship. Inspired by the leaf-shaped blades of Japanese spears, each hand features one mirror-polished surface and one satin-brushed plane. As they move across the dial, they alternately reflect and soften the light, ensuring exceptional legibility while adding another layer of visual depth.
At the Heart of Motion: The Floating Mechanics
At six o’clock, the flying tourbillon introduces the dial’s only continuous movement. The aperture is deliberately restrained, allowing the mechanism to remain naturally integrated within the overall composition rather than dominating it.
Above the aperture sits a slender satin-finished bridge. While it appears to support the mechanism, its purpose is intentionally different. Because the flying tourbillon is supported entirely from beneath by a single bearing, there is no need for an upper support. Instead, the bridge acts as an architectural frame, balancing the composition while preserving the illusion that the rotating cage floats freely beneath the crystal. It is a subtle decision, but one that perfectly reflects Hitori’s design philosophy, where every line exists with purpose rather than ornament.
The three-armed tourbillon cage, secured by heat-blued screws, completes one full rotation every minute as the balance and escapement revolve together in perpetual motion. More than two centuries after Abraham-Louis Breguet first conceived the tourbillon, it remains one of watchmaking’s most captivating mechanical achievements. Today, it is admired less as a solution to precision and more as a celebration of craftsmanship, mechanical ingenuity, and the beauty of motion itself.
The Re-Engineered Core: Mechanical Equilibrium
Turn the watch over and the Ginga reveals something considerably removed from a conventional automatic movement. The screw-down caseback is fitted with a tinted sapphire window treated with anti-reflective coating, allowing the mechanics to reveal themselves without demanding too much attention. At its heart is the Hitori Calibre HT01, a heavily modified automatic calibre derived from the architecture of the Miyota 8215, one of Japan’s long-established mechanical workhorses. In the Tūrubi, however, that familiar starting point has been extensively reworked around a one-minute flying tourbillon.
Rather than simply placing a complication onto an existing movement, the conventional regulating organ has been replaced by the flying tourbillon at six o’clock, with the escapement carried within its rotating cage and the surrounding architecture modified to accommodate its operation. Most notably, the HT01 does not retain the 21,600 bph frequency of the conventional 8215. Its escapement has been reworked with a modified pallet fork and escape wheel, together with a revised balance assembly, raising the frequency to 28,800 bph, or 4 Hz. The higher frequency places greater demands on the movement’s available energy, resulting in a power reserve of approximately 40 hours. While the HT01 traces its foundation to the Miyota 82 Series, the resulting movement is quite different from the calibre from which it began. There is something fitting about this approach for Hitori.
The flying tourbillon completes one rotation every sixty seconds, continually carrying the escapement and regulating organ through different positions. Historically conceived to average out positional effects caused by gravity, it remains one of mechanical watchmaking’s most fascinating mechanisms. Here, the flying construction removes the conventional upper bridge and supports the cage from beneath, leaving the mechanism almost suspended within the dial. There is certainly theatre in watching it move, but spectacle was never the sole intention. The tourbillon was considered as part of the Ginga’s architecture from the beginning, allowing it to sit naturally within the dial while preserving the compact 39mm proportions and everyday character of the watch.
Through the caseback, another distinctly Hitori element comes into view. The customised metallic winding rotor is decorated with a traditional Japanese wave motif, introducing texture and movement while remaining harmonious with the rest of the watch. Subtle variations in its metallic hues mean that no two rotors appear entirely identical. Inscribed upon it is a passage from Japanese poet and calligrapher Mitsuo Aida:
「人生において 最も大切な時 それはいつでも いまです」
“In life, the most important moment is always now.”
Geometry with Purpose — The Kozane Bracelet
The design language of the Nexus extends naturally beyond the case into the Kozane Bracelet, named after the kozane, the small overlapping scales that formed traditional Japanese yoroi armour. Like the case itself, the bracelet is shaped around the principle of layered construction, where each link overlaps the next with quiet precision. Rather than existing as a separate component, it flows seamlessly from the sculpted lugs, creating a continuous silhouette that appears carved from a single piece of steel. Every proportion, transition, and facet was carefully considered to balance crisp geometry with fluid articulation, allowing the bracelet to wear with remarkable comfort while remaining visually composed.
The finishing follows the same philosophy. Broad satin-brushed surfaces establish the bracelet’s quiet character, while sharply defined mirror-polished bevels frame every edge, allowing light to travel naturally across each link as the wrist moves. It is a restrained expression of craftsmanship, one that reveals itself gradually rather than all at once. Nothing exists for decoration alone. Every surface, every chamfer, and every transition contributes to a bracelet that complements the watch instead of competing with it.
Measuring 20 mm at the lugs before tapering gracefully towards the clasp, the Kozane Bracelet sits close to the wrist with exceptional balance. Every individual link is meticulously finished using Hitori’s signature combination of directional satin brushing and crisp mirror-polished bevels, echoing the sculptural language of the case while allowing the bracelet to articulate with surprising fluidity. Like the Nexus itself, it was designed not to demand attention, but to quietly reward those who appreciate thoughtful design and enduring craftsmanship.
Completing the Kozane Bracelet is a Musubi clasp developed specifically for the Tūrubi, designed to feel like a natural continuation of the bracelet rather than an afterthought. Its broad brushed surface and restrained proportions allow it to disappear into the overall design, while a concealed tool-free micro-adjustment mechanism provides everyday adaptability without interrupting its clean form. The subtle 「ひとり」 engraving serves as the only visible signature, reflecting Hitori’s belief that the finest details are often those that reveal themselves only after years of ownership.

Beyond the Passing Seasons: A Milestone of Craft and Spirit
“Over the years, we’ve come to realise that time itself is the greatestteacher in watchmaking. Not only the time displayed on the dial, but theyears spent refining an idea, living with it, and learning when to leave something untouched. A well-made watch is never rushed. It is shaped bypatience, conviction and care. That rhythm belongs to monozukuri, not marketing.”
Producing the Ginga Tūrubi requires significantly more time than any previous Hitori project. Every movement demands careful adjustment, while each case and bracelet undergoes an extensive finishing process
before final assembly in Japan.
For that reason, production is limited to just 50 pieces worldwide. Perhaps that is what makes the Ginga Tūrubi meaningful. It is not simplynabout owning a tourbillon, but about owning a chapter in Hitori’s journey.
The finishing differs from the Yoshino and the architecture departs fromthe Nexus. Even the movement follows a different path. Yet every decision remains guided by the same belief that has shaped every Hitori watch—to create objects that are honest, enduring and a genuine pleasure to wear.
