In the mid-1950s, Tsuneya Nakamura asked his chief administration that he makes another advanced watch to return Seiko on the horological map.

This is the means by which the Seiko Marvel was brought into the world in 1956, totally made by the (at that point) 33-year-old Tsuneya Nakamura.

But past the modern and monetary effect the Marvel had, it prepared for some incredible accomplishments for Seiko in the coming decade.

The Marvel won numerous homegrown chronometry challenges, motivating Tsuneya Nakamura to become a significant entertainer in the worldwide watchmaking industry.

From the Marvel, Suwa Seikosha made the Gyro Marvel, the absolute first programmed watch produced in Japan under the aegis of Nakamura san. This watch was furnished with the celebrated “Sorcery Lever” framework, that is as yet being used in pretty much every programmed watches made by Seiko today.

The project was normally given to the 38 years of age Tsuneya Nakamura, the man behind the unbelievable Marvel. He was placed accountable for making, creating and dispatching what immediately became – and still is – Seiko’s leader brand.

Lord Marvel and Crown combined

The first Grand Seiko (otherwise known as the First) was the combination of two meaningful looks for Suwa Seikosha. For the feel, the First takes its motivation fundamentally from Lord Marvel, an extravagance rendition of the Marvel (hand engraved dial, jewel cut gold hands and records), and for the development, it takes its motivation predominantly from the Crown, whose type will be additionally refreshed to make Seiko’s first “Chronometer” grade watch, the Grand Seiko First and its cal.3180. Two of Tsuneya Nakamura’s best manifestations combined into a watchmaking masterpiece.

Olympic Games ’64

The mid 60s additionally mark the start of a significant move made towards the extremely encouraging quartz innovation. Simultaneously, Seiko is picked to be the authority clock for the Tokyo 1964 Summer Olympic Games.

It’s under Nakamura’s direction that mechanical and electronic designers buckled down, inseparably, to make the Quartz Crystal Chronometer, the world’s first compact quartz clock. This miracle of innovation was introduced to the 1963 Neuchatel chronometry preliminaries in the “Marine Chronometer” classification, a first for a Japanese brand. It got the 10th spot, a good score for Seiko’s first dish in this celebrated challenge.

On the very year, this clock and its varieties were comprehensively utilized for the Tokyo Olympics and Tsuneya Nakamura assumed a conclusive part in beginning another time for sports timing, with both the utilization of quartz and the new mechanical stopwatches made for the event and that arrived at a never accomplished accuracy.

For the 1964 Olympics, Seiko likewise delivered their first chronograph wristwatch, the Crown Chronograph with a monopusher hand-wound development cherished by each Seiko authorities out there.

Very Fine Adjusted

Even however the “Quartz Crystal Chronometer” may appear to be an episodic piece of Seiko’s set of experiences, it exemplifies three of Seiko’s most significant accomplishments during the 60s: the Swiss chronometry competition, the 1964 Tokyo Olympics Games and the improvement of quartz innovation. Also, behind those three accomplishments, as yet unchanged man…

The interest in the Swiss chronometry preliminaries was Tsuneya Nakamura’s thought, a man that could compare constantly his work with the business chiefs to consistently push ahead. This is the thing that guided him through the formation of the Marvel, this was the establishing thought of Grand Seiko and the actual embodiment of their support in Swiss chronometry competitions.

Grand Seiko was a tremendous achievement, with its pinnacle being the creation in 1969 of the unbelievable VFA (Very Fine Adjusted), legendary watches in Seiko’s set of experiences, controlled to inside +/ – 2 s/d (really +/ – 60 sec/month) with an assurance of two years, a totally momentous watchmaking.

Chronometer Competition

The chronometry preliminaries were additionally an incredible accomplishment for Suwa Seikosha as they in a real sense shook the Swiss watchmaking industry in 1968.

On the 5th of May 1968, the Council of Neuchâtel reported they dropped the watch class of the chronometry preliminaries yet they actually gave the consequences of the watches submitted up to that point. Suwa Seikosha submitted two developments that got the second-best appraising ever for this classification, the record actually being held by Omega from the past year.

When the crossing out was reported, they chose to send some different developments to the Geneva chronometry preliminaries and they won spots four to ten, the platform being held by quartz models, and the primary spot in the assembling positioning. Their best scoring development in Geneva squashed Omega’s Neuchâtel 1967 record.

After this tidal wave, the guidelines changed and just European fabricates were permitted to take an interest in Swiss chronometry trials.

Starting toward the finish of the 1950s, the R&D groups at Suwa Seikosha buckled down of building up the quartz innovation and their first accomplishment was the dispatch of the Quartz Crystal Chronometer in 1963. The greatest test was scaling down, and with it came another central point of interest: the force save. The principal quartz wristwatch models had an exceptionally short force save and the batteries would bite the dust in no time.

Knowing the Swiss were gaining acceptable ground with the Beta21 project, Seiko’s CEO gave Tsuneya Nakamura a final offer toward the finish of 1968: he needed to deliver the world’s first quartz wristwatch before January first 1970. Furthermore, since the test was not hard enough, he alloted the entirety of the specialists chipping away at quartz to different ventures and let Tsuneya Nakamura framing new groups that would have one year to deliver their quartz wristwatch.

And this is when Nakamura san settled on a decision absolutely critical, a decision that would help tackle the force hold issue, the decision to utilize a stepper engine that would move the second hand once consistently. This decision may appear to be inconsequential today yet this is the thing that figured out what might the norm for quartz watches be as, as it were, the model created by Tsuneya Nakamura utilizing a stepper engine will fill in as a source of perspective for the entire business and billion of watches will be made utilizing a similar standard in the accompanying decades.

He likewise handled the ozone-draining substances issue, carrying new answers for the table, particularly concerning CFCs, an exceptionally huge exertion that procured him six back to back «Stratospheric Ozone Protection Awards» (both Corporate and Individual Awards) from the U.S. Ecological Protection Agency.
