Overview
Metalor Technologies, originally known as Métaux Précieux SA Metalor, is a Swiss precious-metals company whose roots date to a preparatory rolling mill established in Le Locle in 1852. The original business was associated with the melting of gold and the manufacture of watch cases, reflecting the importance of precious metals to the historic Swiss watchmaking economy. Over time, the company developed from a local metalworking operation into a multinational group involved in precious-metals refining, alloy production, bullion manufacturing and other related processes. The company’s early institutional history was closely connected with Swiss finance. In 1864, the Le Locle plant was acquired by the Banque du Locle. The business later became part of the Swiss Bank Corporation in 1918. During the following decades, its activities expanded beyond the production of watch-related components to include the refining of precious metals and the manufacture of bullion. In 1936, the bank association established Métaux Précieux S.A. Metalor, creating the corporate identity under which the company became more widely known. Metalor subsequently broadened its manufacturing and refining footprint outside Switzerland. A refinery in Hong Kong began operations in 1982, followed by activity at a United States refinery in 1986. This international expansion allowed the company to serve customers in major jewellery, industrial and precious-metals markets while remaining closely associated with Swiss technical expertise. Its product scope also moved beyond traditional watchmaking. The company became a supplier of alloys and other precious-metal materials to watch and jewellery manufacturers, including Swiss watch brands, while extending into applications and procedures outside its original core sector. The ownership structure changed substantially during the late twentieth and early twenty-first centuries. After the 1998 merger of Swiss Bank Corporation with Union Bank of Switzerland, a majority interest in Métaux Précieux SA Metalor was acquired from SBC by a group of Swiss private investors. The company adopted the name Metalor Technologies in 2001. French investment firm Astorg Partners later became the majority shareholder, holding 50.5% before the subsequent sale of the business. In 2013, Metalor selected Singapore for a new gold refinery and bullion-manufacturing facility. The location was intended to support rising regional demand for gold and Singapore’s effort to strengthen its position as a global centre for physical precious-metals trading. The facility opened in June 2014, adding an important Asian production and distribution base to Metalor’s existing international network. In September 2016, Tanaka Kikinzoku, a Japan-based group specialising in precious-metals production, acquired all of Metalor. The transaction placed the Swiss company within a larger international precious-metals group while preserving Metalor as a distinct operating brand. Metalor’s business is therefore best understood as a specialist B2B materials and refining brand rather than a consumer jewellery label. Its customers and partners include industrial users, jewellery and watch manufacturers, bullion-market participants and other organisations requiring processed, refined or alloyed precious metals. The available reference material does not provide a current executive roster, detailed financial information or a complete list of present facilities and markets.
History
Metalor’s history begins in 1852 with the establishment of a preparatory rolling mill in Le Locle by Martin de Pury & Cie. The operation specialised in melting gold and making watch cases, placing it within the industrial ecosystem that developed around Swiss watchmaking. In 1864, when the plant employed five people, ownership passed to the Banque du Locle. The enterprise later entered the orbit of Swiss banking. In 1918 it became the property of the Swiss Bank Corporation. Under this ownership, the business expanded its activities to include precious-metals refining and bullion production, moving beyond the narrower role of a watch-case and metalworking operation. In 1936, the banking association established Métaux Précieux S.A. Metalor in Le Locle. Production was subsequently expanded at the Neuchâtel site and later at facilities outside Switzerland. Internationalisation became an important part of the company’s development. Metalor opened a refinery in Hong Kong in 1982 and began operating a refinery in the United States in 1986. These facilities supported the company’s growing role as a supplier of refined precious metals, alloys and related products to customers in multiple regions. Although watchmaking and jewellery remained important markets, the company also expanded into broader industrial and technical applications. A major ownership transition followed the 1998 merger of Swiss Bank Corporation with Union Bank of Switzerland. A group of Swiss private investors, including Ernst Thomke, Martin Bisang, Rolf Soiron and Giorgio Behr, acquired a majority of Métaux Précieux SA Metalor from SBC. In 2001, the group changed its name to Metalor Technologies, signalling a broader international and technology-oriented identity. Astorg Partners later became the company’s principal financial owner. Before the 2016 transaction, Astorg held a majority stake of 50.5%. In September 2016, all of Metalor was sold to Tanaka Kikinzoku, a Japanese precious-metals group. The acquisition integrated Metalor into a larger global platform while retaining the Metalor name and its Swiss industrial heritage. Metalor also expanded its Asian presence during this period. In 2013, it chose Singapore for a new gold refinery and bullion-manufacturing facility. The decision was associated with growing regional demand and Singapore’s policy objective of becoming a major centre for physical gold and precious-metals trading. The refinery opened in June 2014. The available reference material does not establish a complete current corporate structure, executive list, financial profile or detailed catalogue of facilities. It does establish Metalor’s continuing identity as an international B2B precious-metals company serving refining, bullion, alloy and specialist manufacturing needs.
