Pendant Lamp: SEIKO (Seiko) Japan watch factory visit note [a] SII headquarters

At the end of October 2016, Love Table family website was invited to fly to Japan to visit the famous Japanese watch brand --- SEIKO watch factory.

SEIKO (Seiko) was founded in 1881, has 135 years of history. Founder Mr. Kim Tae-ro has a clear vision, he hoped SEIKO (Seiko) as "always one step ahead" leader. 'Moving ahead.Touching hearts.' Become the company's fundamental belief. Under the guidance of this belief, SEIKO (Seiko) has made countless first watchmaking industry:

In 1892, founded the factory 'Seiko homes', the production of Japan's first wall clock;

1895, making Japan's first pocket watch;

1913 SEIKO created the first Japanese-made watch "Laurel";

1955, Japan's first production of automatic mechanical watches;

1969, released the world's first quartz watch ASTRON 35SQ; set off a worldwide quartz watch revolution;

1998, released the world's first SPRING DRIVE movement watch;

In 2012, SEIKO ASTRON released the world's first GPS solar pointer watch.

Not known to the public, Seiko watch business is just the tip of the iceberg floating on the surface, which gradually derived from the core watch business a huge business group --- printers, computers, projectors, industrial robots, semiconductors, LCD, Glasses and so on. The watch manufacturing business, mainly in Seiko Instruments Inc. (SII) and Seiko Epson Corporation (SEC) --- You're right, Epson is famous printer, it is actually Seiko Holdings.

Now, please visit the SEIKO factory together with your loved one.

First of all, we came to Seiko Instruments Inc. (SII) headquarters in Chiba Prefecture, not far from Tokyo. Now SII manufactures mechanical watches, including the high-end Grand Seiko and even some of your Credor watches, as well as the Prospex dive watch And even the median price of the Presage watches.

Introduce the history of SEIKO and the history of Seiko mechanical watches

Some Grand Seiko watches on display

SII side highlighted the Grand Seiko watch the development process, and excellent quality:

Grand Seiko Seiko pioneered in 1960, the high-end watch series, on behalf of the SEIKO (Seiko) top watchmaking process, the pursuit of high precision, legibility and durability, has been limited to Japan and a very small number of local sales, Years ago formally formally sold in the world.

Seiko has always called for a step ahead, reflected in the GS is a higher standard than the Swiss watch COSC certification:

The daily difference is -3 ~ +5 seconds / day, compared with the COSC standard is -4 ~ +6 seconds / day;

Three temperatures (8 degrees, 23 degrees, 38 degrees) under the conditions of the test, compared to only 8 degrees and 38 degrees COSC conditions, this is because Seiko found most of the balance spring performance temperature curve does not change linearly;

6-position test, COSC only 5-position test, Seiko more 12 o'clock position;

Test period up to 17t days, while the COSC standard is only 15 days;

As a result of such stringent requirements, Grand Seiko watches become the pride of Japan's Seiko manufacturing.

Subsequently, SII party to Grand Seiko's 9S85 series mechanical movement, for example, to explain one of the black technology.

GS9S85 mechanical movement of high-frequency movement, high frequency to bring high precision, but in general, a great energy loss; Seiko technicians in order to protect the movement of the long-lasting operation, improve transmission efficiency and reduce energy consumption, from three aspects Start:

1. Escapement system using MEMS MEMS machining technology;

Escapement escapement and escapement fork hollow, the processing surface finish is improved, the gear teeth into a special L-shaped, can reduce energy consumption (the picture shows the comparison of common parts and MEMS processing parts);

2. More advanced Spron hairspring;

Seiko is the world's few handmade gossamer neng watch brand since the 1950s has been using its own production Spron hairspring, 9S85 series movement is more applied the latest Spron610 hairspring, anti-magnetic capacity of up to 10,000 Gauss! Shock and durability Also improve a lot;

Engineers even tweeted directly with old tweezers Sprane200 hairspring and the new Spron610 hairspring, showing a lot of its modulus of elasticity increased.

3. New self-winding device --- Reverser commutator!

Seiko developed a unique new winding device --- Reverser commutator, it is very small lean, the efficiency of the chain than the traditional magic lever is also high, while greatly reducing the space. This stuff is very small, probably that small mung bean is so big. Think about the other home's chain device size.

At the same time, SEIKO also changed the new spring Spron530, adding a wheel in the middle of the wheel, all of these technologies are Seiko long-term research and testing from their own, put an end to the shortcomings of the traditional high-frequency movement.

The high-end Seiko Instruments Inc. (SII) mechanical watches are assembled in the Shizuku-ishi Watch Studio 雫石高工時間工作室. SII headquarters in both high-end real stone studio branch, is mainly responsible for hand-decorated high-end mechanical watch assembly, but also in 2016 Seiko famous Fuguaku Fu Yue Tourbillon limited edition watch the birthplace of!
