CONCEPT

55 years ago, Seiko introduced its, and Japan’s, first ever diver’s watch. With an automatic movement and water resistance to 150m, it proved its reliability when it was used by the Japanese Antarctic Research Expedition team in the 1960s. In the years that followed, Seiko created many other diver’s watches that found favor with professional divers and adventurers alike, thanks to their high quality and reliability.

These two special limited editions the celebrate of the 55th anniversary of the very first Seiko diver’s watch. Based on landmark designs from 1965 and 1970, these watches have been created with Seiko’s very latest technologies and new, higher specifications.

SEIKO Prospex SPB183J1 is 1970 Diver’s Modern Re-interpretation

Seiko Prospex SPB183J1 Model

 

A unique profile and a proud history

Five years after the first Seiko diver’s watch, a new design was introduced that was as instantly memorable as it was supremely functional. For extra security, the crown was moved to the four o’clock position and protected by an asymmetrical case design. The rotating bezel was unidirectional with 120 clicks and a 60-minute scale. Today, this 1970 classic is re-created in blue with a powerful 6R movement and an updated design.

Naomi Uemura – adventurer

Naomi Uemura

Naomi Uemura was born in 1941 in Toyooka City in Japan’s Hyogo Prefecture. His love affair with adventure began when, at Tokyo’s Meiji University, he joined the Alpine Society. By the age of 30, he had climbed Mt. Kilamanjaro, Mont Blanc and the Matterhorn and, in 1970, he became the first Japanese mountaineer to reach the summit of Mt Everest. He went on to become the first to climb the tallest peaks on all five continents the same year. In 1978, with nothing more than a sled and dog team, he trekked for 56 days to become the first man to reach the North Pole solo. In the winter of 1984, he succeeded in climbing Alaska’s Denali (then known as Mt McKinley) in winter but disappeared on the descent. Famed for his modesty as much as his achievements, Uemura became a national hero in Japan and was given the National Honor award shortly after his death.

Design
A unique design faithfully recreated.

The new Prospex re-creation of the 1970 original is slightly smaller than the original but faithful in every other respect to its design. The case has the same distinctive asymmetrical shape to protect the crown at the 4 o’clock position.

The re-creation is powered by Caliber 6R35 which delivers a power reserve of 70 hours. The case has a super-hard coating and the crystal is a dual-curved sapphire with anti-reflective coating. The watch is 200 meter water resistant and the bracelet has an extender for use when diving in a full wet suit. The upper surface of the bezel is Zaratsu polished to a perfect mirror finish.

About Seiko Prospex Sea Diver SPB183J1

From the introduction in 1965 as Japan’s first diver’s watch, the engineers never stopped to innovate. The trust this watch has gained goes beyond the borders of Japan and into the world. Because of that, Seiko facilitated the establishment of the standard for diver’s watches in International Standard Organization (ISO), and Japan Industrial Standards (JIS). As for the ISO, Seiko lobbied the organization to amend the standard to match the actual use of diver’s watches in the deep sea. In 1996, ISO6425 with annex, about diver’s watches for mixed gas diving, was issued. Moreover, Seiko’s relentless challenge and innovation have driven the company to create a model that could truly be called authentic.

Behind Seiko’s diver’s watch that has been chosen by divers world wide, there are qualified engineers who work to developed technology that the world has never seen.

First, through significant innovation, water resistance and impermeability has proven to be the finest in world class. Above all, along with functionality, using specialized material and precise detail in structure, the timepiece is made to perfection. In addition, Seiko’s determination and innovative technology resulted in many patents to preserve the company’s authenticity.

Since then, there are countless products labeled as a diver’s watch around the world but only a negligible number of these timepieces are functional in professional environments.

History of Seiko Prospex Sea Diver SPB183J1

Introduced in 1965, Seiko’s innovative diver’s watch has been chosen by divers and adventurers globally. In other words, Seiko’s diving watch has become a global standard as a result 50 years of innovation.

Everything started with a letter from a professional diver in Hiroshima prefecture of Japan. However, the diver explained that in depths greater than 300 meters, when using a diving capsule and saturation diving techniques, most watches get damaged. Answering this request, Seiko established a new development team. Then after years of research development, the world’s first Professional Diver’s 600 m with titanium case was created.

In conclusion, with half a century of history and remarkable innovation, Seiko’s diver’s watch has been used all over the world in diverse situations. Therefore, over the years, the timepiece has proven itself worthy of any harsh environment and has been praised from professional divers.

Earning credibility through vigorous adventures in the North and South Pole.

From 1966, the timepiece has been brought on 4 missions with the Antarctic Team of the Geospatial Information Authority of Japan. Later on, numerous adventurers and explorers have made achievements such as successfully ascending Everest gearing Seiko’s diver’s watch. After years of proving itself worthy of withstanding extreme environments, Seiko’s diver’s watch has earned its integrity.

Exceeding any expectation of water resistance with the depth of 1062 meters.

In May of 1983, two Professional Diver’s 600 meters were mounted on Shinkai 2000, a research submersible used by JAMSTEC (Japan Agency for Marine-Earth Science and Technology). The watch was originally intended for use up to 600 meters, yet the timepiece withstood water pressure at a depth of 1062 meters. As a result, the watch’s legibility, precision, and exterior remained unscathed, continuing to strengthen its credibility.

The vertical line shows the pressure inside the watch case and the horizontal line indicates the period of time.
After the dive, the air pressure inside the watch case gradually went up.
Seiko Professional diver’s scored the best result and verified that it is strong enough to function even at great depths.

Proving its significant impermeability.

For saturation diver’s watches, helium is a constant issue. That is to say, the gas penetrates the glass, and in some cases the difference in external and internal air pressure causes the glass cover to break. While other companies focus on methods to release Helium with an escape valve, Seiko took a different turn and developed a glass case that is practically impermeable to Helium gas. This is the creation of Seiko’s Diver’s Professional 600M. Then, in 1983, JAMSTEC conducted an impermeability test by submersing several diver’s watches under 300M saturation diving. Consequently, Seiko’s Diver’s Professional 600M proved to be up to ten times more impermeable to Helium gas compared to other companies. In short, the true diver’s watch continues to prove itself.

History of Seiko

The company was founded in 1881, when Kintarō Hattori opened a watch and jewerly shop called “K. Hattori” (服部時計店 Hattori Tokeiten) in the Ginza area of Tokyo, Japan. Eleven years later, in 1892, he began to produce clocks under the name Seikosha, meaning roughly “House of Exquisite Workmanship”.

The first watches produced under the Seiko brand appeared in 1924. In 1969, Seiko introduced the Astron, the world’s first production quartz watch, it cost the same as a medium-sized car. Seiko later went on to introduce the first quartz chronograph.
