Seiko

From the official website: "The story of Seiko began in 1881, when a 21 year old entrepreneur,
Kintaro Hattori, opened a shop selling and repairing watches and clocks in central Tokyo.

Today, after more than 130 years of innovation, Kintaro Hattori’s company is
still dedicated to the perfection that the founder always strove to achieve."

Seikosha builds the first pocket watch.

Throughout the 1890's, the success of Seikosha's wall clock business increased, and Kintaro looked to broaden the range of his business. In 1895, he created a pocket watch, the Timekeeper. It was a vital step forward, without which the future of Seiko would have been very different as it paved the way for Japan's first ever wrist watch.

Jacquet Droz

From the website:

EIn 1774, Pierre Jaquet-Droz decided to set up a workshop in London, a hub for industry and trade, under the management of his son, Henri-Louis. Completely exhausted by his travels, the latter delegated some of his responsibilities to Jean-Frédéric Leschot. Leschot was tasked in particular with overseeing the business relationship with the prominent trading company James Cox London, whose agents in Canton opened up the Far Eastern market for the Jaquet-Droz Company and for many years represented it in China, India and Japan. Pierre Jaquet-Droz always had a passion for nature and birds whicFor some ten years, the company continued to expand. It sold clocks, automata, watches and singing birds all over the world, especially in China. But the harsh climate of La Chaux-de-Fonds and the insidious London fog was detrimental to Henri-Louis’ precarious state of health. In 1784, he decided to move to Geneva, finding its artistic and literary life to his taste. Jean-Frédéric Leschot soon joined him and they decided to open the city’s first clockmaking manufacture, simultaneously introducing the production of timepieces featuring grand complications. The talent and interest shown by Henri-Louis Jaquet-Droz and Jean-Frédéric Leschot in the civic life of Geneva was quickly noted and approved of. The City of Geneva presented both of them with the coveted Bourgeois d’Honneur Award, and welcomed their involvement in municipal activities. Jaquet-Droz was admitted to the newly reinstated Société des Arts, and was very active in the advancement of technical training. He helped set up a factory-school in Geneva to make cadratures for repeater watches and developed many projects bearing on watchmaking technique and advocating the professions associated with watchmaking. Pierre Jaquet-Droz moved into the house of a clockmaker named Dental, at the corner of Rue Molard and Rue du Rhône, which housed the workshops and his son’s apartment.h he transcribed through his clocks, snuff boxes, pocket watches and automata.
