We are pleased to announce that,
starting on January 1, 2023, Adamant Namiki Precision Jewel Co., Ltd.
will be rebranded as Orbray Co., Ltd.

Over the more than 80 years since our founding, we have introduced a variety of products based on our strengths in precision processing technology: cutting, grinding, and polishing. In 2018, we merged our group companies Namiki Precision Jewel Co.,Ltd. and Adamant Co.,Ltd. and changed the company name to Adamant Namiki Precision Jewel Co.,Ltd. Our most important task now is to ensure that the integrated company is more powerful than the individual companies had been. We aim to accelerate our growth into the future under the new management structure that was inaugurated in April 2021. To this end, we have decided to change the name of our company, which had been named after our founder and the original business, to one that is more appropriate for a company that has developed a wide range of businesses and is advancing toward a boundless future. Uniting all of our employees under the new company name and corporate identity, we hope to spark a renewed sense of dedication to an even brighter future.

    Namiki Seisakusho founded to manufacture jewel bearings made from synthetic sapphire.

    Namiki Seisakusho founded to manufacture jewel bearings made from synthetic sapphire.

    Founder Kazu Namiki was asked by an acquaintance to manufacture jewel bearings for electric meters, and founded Namiki Seisakusho to do so in 1939. Until then, most synthetic gemstones had been imported, but around that time a Japanese manufacturer succeeded in synthesizing sapphire, which triggered full-scale domestic production of industrial jewel parts.
    When war broke out, the company was designated as an essential industry for the military, as it engaged in the development and manufacture of advanced parts such as jewel bearings for flight instruments and navy radio apparatus.

    Began manufacturing record styli, and supplied half of the global market.

    Began manufacturing record styli, and supplied half of the global market.

    As Japan’s post-war recovery proceeded, more and more people became able to afford such luxuries as enjoying music through vinyl records.
    Thus, we began to utilize our manufacturing and processing technology to produce record styli made from sapphire. Our record styli proved to be popular all over the world, and at one point Namiki held half of the global market for record styli.
    Further responding to consumer demand for products that had previously been luxury goods, we began manufacturing ruby jewel bearings, which replaced the glass components that had previously been used. With the advent of these new wear-resistant components, watches became able to keep track of time more accurately than ever before.

    Made wristwatches stronger, more durable, and more beautiful.

    With Japan’s further economic development, as symbolized by the Tokyo Olympics in 1964, wristwatches became increasingly popular as part of ordinary people’s daily lives. At that time, the mainstream watch crystal was made of scratch-resistant plastic. When we were asked if we could make a stronger watch crystal, we developed one made of hardened glass. For example, we made the one that was used in Citizen’s Crystal Seven, the much-loved wristwatch that did not scratch easily or break even when dropped.
