On 14 May 2025, Aytystyle attended the exclusive launch of Naoya Hida & Co.’s 2025 collection in a sunlit atelier tucked away in Tokyo’s Kyobashi district. At precisely 11:00 AM, founder Naoya Hida unveiled eleven references, including three new models and two new D-buckles. The centerpiece is the NH TYPE 6A, a 37mm dress watch powered by the Cal. 3025PC, a hand-wound perpetual-calendar movement developed in collaboration with Swiss and Austrian partners. This launch highlights Naoya Hida & Co.’s blend of meticulous craftsmanship and innovative watchmaking.
“Cal. 3025PC is the product of three workshops speaking the same language of precision. Dubois-Depraz provides the perpetual-calendar intellect, Habring² the beating heart, and our Tokyo atelier the finishing soul—bridges, click springs, screws, the tiny details that let the watch carry our own signature.”

A hand-wound perpetual calendar in 37 millimetres
The NH TYPE 6A distils an age-old grand complication into a case scarcely wider than a two-rand coin. Its Cal. 3025PC movement marries a Dubois-Depraz perpetual-calendar module to Habring²’s A11B gear train, while Naoya Hida’s Tokyo workshop fashions proprietary bridges, click springs and even the screws before undertaking final assembly and regulation. The result is a slim 11.5 mm profile that nonetheless delivers a full calendar—day, date, month and leap year—displayed on a sterling-silver dial whose Roman numerals and sub-dial markings are individually hand-engraved by master artisan Keisuke Kano. Yellow-gold hands supply warmth; heat-blued steel pointers lend contrast, and the manually wound calibre beats at 4 Hz for roughly 45 hours between windings, giving collectors a rare blend of compact proportions and haute-horlogerie complexity.
Conceived to compress pocket-watch grandeur into wristwatch proportions, the 3B-3 exchanges its predecessor’s steel for a full 18 K yellow-gold case and crown. Eleven Roman numerals and the expressive moon face are hand-engraved; the night sky is a disc of natural lapis lazuli. Only five pieces will be made across 2025–2026.
If the 3B-3 evokes the Enlightenment, the 5A-1 leans into mid-century modernism. A newly tooled acrylic crystal—cut high and faceted like vintage plexi—crowns a two-part German-silver dial whose Breguet “12” floats above concave dolphin hands. At 33 × 26 mm and 9.1 mm thick, the stainless-steel case channels dress-watch elegance for smaller wrists.
Owners have long praised Naoya Hida’s 32-length strap-sampling ritual; now the buckle follows suit. Two sizes (40 mm and 45 mm total length) feature a subtly re-profiled curvature that pulls the strap closer to the wrist’s underside, reducing “strap-flare” on slimmer arms.
Observation to Collaboration
Mr Hida first admired Habring²’s Felix series in 2015 but had no direct line until 2022, when mutual friend Max Büsser introduced him to Dubois-Depraz for a perpetual-calendar talk. Discovering that the Swiss specialist produced a 7750-compatible module solely for Habring², Dubois-Depraz brokered an introduction. By 2024, NH watchmaker Kosuke Fujita was spending a week in Austria, lathes humming in three languages.
Why it matters
In an era when algorithms increasingly dictate production and homogeneity threatens to flatten high watchmaking, Naoya Hida & Co.’s 2025 line-up reminds us that a watch can still be a dialogue—between workshops, between centuries-old craft and modern engineering, and ultimately between maker and wearer. Whether it is the whisper-thin bend of a gold minute hand or the shared heartbeat of three independent ateliers, every detail in this collection argues that intimacy and intent are the true hallmarks of luxury. For collectors willing to look beyond mass prestige, the pieces unveiled today won’t simply mark time; they will mark a moment when collaboration and hand-wrought artistry reclaimed the future of the mechanical wristwatch.
