A company whose main business was printers created a movement innovation rarely seen in the watch industry. This alone is baffling, but surrounding this single watch, there are three distinct paradoxes.
In December 1999, a watch powered by the Spring Drive 7R68 movement was released in Japan in a small batch under Seiko’s high-end brand Credor. Most enthusiasts never even saw one in person. The movement kept daily accuracy within plus or minus one second, but what truly transfixed onlookers was the seconds hand: neither the micro-vibrations of a mechanical balance wheel ticking several times per second, nor the one-step-per-second jump of a quartz watch. It simply glided across the dial silently, seamless and smooth. This was the first incongruity.
Then there was a man: Yoshikazu Akahane, an engineer at Suwa Seikosha. In 1977, he conceived the regulation scheme. In 1982, he built the first working prototype, only to hit a wall—technological conditions simply did not allow further progress. This stall lasted for over a decade. By the time the product reached the market, Akahane was gone: he passed away from illness in August 1998 at the age of 52. From conception to its market release in late 1999, the journey spanned 22 years; Akahane devoted the first 21 of them to it.
Finally, the last detail. Suwa Seikosha, the maker of this high-precision watch, was primarily in the printer business. In 1968, the factory developed the compact electronic printer EP-101, and its subsequent product line was named Epson, meaning “Son of EP.” While watch collectors were studying the era of this movement, its parent entity was delivering inkjet printing equipment to offices worldwide.
All three facts point to the same mountain factory in the Suwa Basin of Nagano Prefecture. The origins of this factory are intertwined with the entrepreneurial history of the Seiko empire setting out from Ginza.
Tokyo, Ginza, 1881. Seiko founder Kintaro Hattori established K. Hattori, a watch shop starting with retail and repair, gradually laying the groundwork for Japan’s domestic watchmaking industry. Half a century later, the shop had expanded into a massive empire. Seiko’s expansion path differed completely from the centralized workshop model of Europe, resembling cell division instead: in 1937, the watch manufacturing department split off into Daini Seikosha; in 1942, as war approached Tokyo, the Hattori family evacuated part of their production capacity to the mountainous Suwa Basin in Nagano Prefecture to safeguard core equipment and capacity, co-founding Suwa Seikosha with local investors.
This wartime evacuation unexpectedly shaped the factory’s engineering DNA. Winters in the Shinshu mountains were snowy and harsh. The workers recruited were mostly local farm youths. Operating independently from the Tokyo headquarters, the engineering team developed a distinct disposition in their secluded environment: a relentless focus on physical precision, endlessly polishing identical components through long winters to push tolerances down to smaller orders of magnitude.
In 1960, this pursuit saw a concentrated release. Suwa Seikosha produced the first-generation Grand Seiko (Caliber 3180), a manual-wind mechanical movement with a total production of around 36,000 units. Its objective was explicit: match Swiss observatory-grade watches in timekeeping precision and serve as Japan’s flagship. To test its craftsmanship, Suwa began competing in the Neuchâtel Observatory chronometer trials in Switzerland starting in 1963, first entering the marine chronometer category with its quartz Crystal Chronometer, and later achieving stellar results in the mechanical category around 1968.
A technical posture anchored to the highest observatory standards was thus established. It was precisely this obsession that drove the mountain factory to launch a rule-changing quartz watch in 1969, and thirty years later in 1999, present yet another solution. Between these two milestones, the industry endured more than a decade of violent upheaval.
December 25, 1969, Christmas Day. Seiko released the Astron 35SQ in Tokyo, the world’s first quartz wristwatch. Development had taken a full decade.
The Astron overturned the core premise long relied upon by mechanical watches. In a traditional mechanical watch, the mainspring releases energy, the balance wheel oscillates back and forth, and the pallet fork periodically arrests and releases the gear train, slicing continuous torque into mechanical ticks. High watchmaking history is essentially a struggle against the physical flaws of the balance wheel: temperature-compensated balance springs, shock absorbers, and chronometer certifications—all to make the balance wheel swing a fraction more evenly. The Astron took a completely different path. A high-frequency quartz crystal replaced both balance wheel and escapement. Once energized, the crystal vibrated tens of thousands of times per second; an integrated circuit divided the frequency down to one pulse per second, driving a micro stepping motor to turn the gears and move the hands. Friction, lubricant degradation, gravitational position—the errors inherent to mechanical components vanished instantaneously before electronic circuitry.
The gold-cased Astron carried a price tag of 450,000 yen. In Japan at the time, that figure equaled a brand-new Toyota Corolla. Constrained by early assembly and component yield rates, only a few hundred units could be produced in the first few months. Yet this microelectronic architecture swiftly shattered the equilibrium: quartz technology baked high precision into a manufacturable, cost-reducible production system, wiping away the competitive moat that mechanical watchmaking had accumulated over centuries of precision refinement.
Over the next decade came the Quartz Crisis. Swiss watchmakers plummeted from roughly 1,600 companies in 1970 to fewer than 600 by the mid-1980s. Industry employment collapsed from 90,000 to 33,000 in 1984. The affordable American watch industry also largely vanished under the pressure.
The most ironic victim of the storm was Seiko’s own mechanical flagship. With quartz watches possessing overwhelming advantages in accuracy and practicality, the mechanical Grand Seiko line—which represented Suwa’s highest mechanical peak—was discontinued in the mid-1970s. The entity that pulled the trigger struck its industry rivals, but first brought down its own painstakingly crafted mechanical benchmark.
Faced with the microelectronic onslaught, the Swiss watch industry was not without foresight. In 1962, twenty Swiss watchmakers jointly funded the Centre Électronique Horloger (CEH) to develop a wristwatch-grade quartz movement—seven years before Seiko launched the Astron. At the Basel Fair in April 1970, the Beta 21 movement developed by CEH made its debut, with roughly twenty Swiss brands participating and eighteen showcasing finished products, represented by Omega’s Electroquartz. Total production of the Beta 21 reached around 6,000 units, its arrival virtually coinciding with the Astron.
Switzerland did not lag in invention. The true barrier lay downstream: industrial manufacturing and product iteration. Originally slated for market release at the end of 1969, the Beta 21 was delayed by manufacturing and packaging issues with its quartz resonators. Japanese firms vertically integrated their semiconductor and machining systems, whereas Switzerland’s multi-workshop joint R&D model could not amortize manufacturing costs in the short term, leading to broken iteration cycles. While laboratory progress was neck and neck, the scales tipped rapidly in the arena of mass production cost and engineering.
Recognizing its cost disadvantage, the Swiss watch industry launched a strategic retreat. On the mass-market side, the Swatch plastic quartz watch was introduced in 1983, capturing younger demographics with avant-garde designs and automated assembly lines to preserve cash flow and manufacturing scale for the whole industry. On the mid-to-high-end market side, a complete value transformation took place. In 1981, Jean-Claude Biver and Jacques Piguet acquired the nearly bankrupt Blancpain, reviving the brand in 1983 with a declaration: “Since 1735, Blancpain has never made a quartz watch, and never will.” The physical purity of mechanical movements became a totem of resistance against electronic fast consumption. In 1996, Patek Philippe launched its Generations advertising campaign, introducing its famous 1997 slogan: “You never actually own a Patek Philippe. You merely look after it for the next generation.” The utility of the watch receded into a secondary role, transformed into a luxury vessel for family heritage and emotional commemoration.
On the technical level, this retreat drew a clear line in the sand. In 2001, Ulysse Nardin introduced silicon escapements in the Freak watch; silicon balance springs and escapements subsequently proliferated across Swiss high-end mechanical watches. The Swiss watch industry embraced high-tech solid-state materials on one strict condition: they must serve to perfect the traditional mechanical balance system. Not a single mainstream Swiss haute horlogerie brand was willing to offer electronic feedback regulation products; replacing the mechanical escapement with electronic circuitry became the industry line. This line gradually hardened into a high wall: the deeper one patched mechanical details inside the wall, the heavier the cost for any brand attempting to cross over and embrace electronic technology.
The commercial outcome of this retreat is evident in trade data decades later. In 2024, mechanical watches still accounted for 78.5% of total Swiss watch export value; high-end timepieces with an ex-factory price above 3,000 Swiss francs represented just 3% of total export volume, yet contributed approximately 39% of total export value. By retreating from direct competition in low-value-added timekeeping tools, Switzerland successfully defended its high-premium luxury niche.
During the exact period when Switzerland was completing its brand transformation, Japanese engineers in the Shinshu mountains embarked on a different technological exploration. Twenty-two years.
In 1977, while working on Seiko’s Twin Quartz calibration movement project, Akahane conceived a design he personally dubbed the “Everlasting Watch”: retain the mechanical mainspring to drive the gear train, eliminate the wear-prone mechanical escapement, and use the constant vibration of a quartz crystal as a reference for precision regulation. Put simply, it converted the mechanical watch’s open-loop control into a closed-loop servo system. Traditional mechanical watches do not measure real-time rate errors, relying instead on component rigidity and manufacturing precision to withstand interference; Akahane’s envisioned movement continuously monitored the gear train’s rotational speed, compared it against the quartz reference signal, and applied subtle electromagnetic braking if it ran fast, or released the brake if it ran slow. Astrophotographers understand this logic intuitively: no matter how precisely an equatorial mount’s mechanical worm gear is machined, open-loop tracking will accumulate subtle drift; only with an autoguider continuously correcting can long-exposure imaging stay sharp.
The theoretical logic was clear, but the bottleneck lay in the power budget. The energy released by a mechanical mainspring is minuscule, leaving only microwatts of power for a micro-electrical system. At the semiconductor level of the late 1970s and early 1980s, no integrated circuit or quartz loop could function on such tiny current. The generator could not supply sufficient starting and sustaining current, leaving the concept stranded on blueprints and experimental rigs, where it lay dormant inside the company for over a decade.
Yet the project did not die. Crucial support came from a seemingly unrelated direction. After introducing the compact electronic printer EP-101 in 1968, Suwa Seikosha rapidly expanded into office printing, establishing the Epson brand. The steady cash flow generated by printer hardware and consumables grew into a pillar business, its profits providing institutional protection and financial support for two decades of frontier R&D with zero commercial return. An inkjet printer sustained a movement.
With the maturation of ultra-low-power CMOS technology, the power bottleneck turned a corner. In 1997, Akahane took charge of the watch development department, fully restarting the shelved project and presenting a technical paper at the Swiss Society for Chronometry. At the 1998 Basel Watch Fair, a prototype featuring the technology was exhibited. Then Akahane passed away from illness at age 52. In December 1999, the movement entered small-batch commercial production under the Credor 7R68 name. To complete this journey, the team built a total of 600 prototypes and filed no fewer than 230 patents worldwide over 22 years. The man who first proposed the idea never lived to see it displayed in stores.
The production movement revealed an unprecedented engineering architecture. It eliminated both the ticking jump of quartz stepping motors and the striking clash of mechanical escapements. The mainspring barrel released mechanical energy to drive the gear train, which rotated a micro magnetic rotor to generate power for the circuitry while simultaneously receiving electromagnetic braking from the IC and quartz circuit. Seiko officially named it the Tri-Synchro Regulator—fundamentally a self-powered closed-loop system using subtle electromagnetic resistance to precisely regulate the mainspring’s unwind rate. The seconds hand showed neither the micro-vibrations of a mechanical watch ticking several times per second, nor the step-and-pause cadence of quartz, embodying the flow of time in a smooth, continuous glide.
The Credor 7R68 was merely the starting point, produced in limited numbers. In 2004, Seiko developed the automatic-winding 9R65 movement, making Spring Drive the core flagship engine of the Grand Seiko brand. Technical stratification within the group followed a distinct hierarchy: the 9R series was reserved exclusively for Grand Seiko; the manual-wind 7R series was kept for Credor’s high-end artistic collections; and the modestly streamlined 5R series was assigned to Seiko’s main line. Epson has never sold Spring Drive movement technology to any third party outside the Seiko Group system. By contrast, standard quartz and mechanical movements manufactured by another specialized movement maker within the Seiko ecosystem are commodity components distributed worldwide.
In 2017, Grand Seiko announced its brand independence, removing the SEIKO name from its dials to face global markets as an autonomous brand, with official pricing anchored firmly in the Swiss mid-to-high-end bracket. In 2024, Grand Seiko explicitly pursued a premium strategy of curbing production volume, selling leaner output at higher price points. Amid a market environment where global luxury watch consumption broadly faced downward pressure in fiscal year 2024, Seiko Group’s watch business still bucked the trend with an 11.7% growth.
Yet there are costs. On the secondary market, transaction prices for popular Grand Seiko models have fallen roughly 37% from their 2022 peak. While Spring Drive helped the brand defend robust gross margins and technological moats on the manufacturing side, it has not yet secured the rock-solid asset recognition on the secondary market enjoyed by heritage Swiss watchmakers. Transforming volume scarcity into universally recognized value retention premiums took traditional Swiss manufactures four decades of cultural accumulation and marketing operations; the re-independent Grand Seiko has been on this path for under ten years.
Looking back across sixty years of industrial shifts, the paradox of this cause-and-effect loop rests in four facts: Suwa Seikosha pulled the quartz trigger; the first bullet destroyed Suwa Seikosha’s own mechanical flagship; twenty-two years later, Suwa Seikosha was the one to forge the new movement antidote; and on financial statements today, this very factory is part of a company whose main business is printers. The Swiss watch industry never trailed in technological invention or precision machining; what truly constrained its steps was the commercial perception it had built for itself: an industry that turned pure mechanical craftsmanship into a religion could not introduce a hybrid product to the market that required publicly admitting an electronic crystal oscillator was superior in accuracy.
Only an enterprise possessing both deep heritage in traditional mechanical machining and foundational mastery over microelectronics and semiconductors could bridge the divide, synthesizing the two into an entirely new form. The fusion of mechanical power and electronic regulation was a natural engineering innovation for such a company. Meanwhile, those who chose to retreat to the mountaintop to defend traditional purity are left to guard an old order within the boundaries of their own making.
