At the time, diving was a relatively rare hobby, so this was a very specialized product. The watch had a bidirectional rotating bezel and was fitted with the automatic Caliber 6217 (17 jewels, 18,000 vph). As its name implies, its stainless steel case was water-resistant to 150 meters, and measured 38 mm in diameter and 13.4 mm thick. It was just one year after releasing the first Japanese-made chronograph that Seiko launched the first dedicated divers’ watch made in Japan, the Seiko Diver’s 150M. The movement was the 12-ligne, 21-jewel Caliber 5719. The Seiko Crown Chronograph had a stainless steel case, 38.2 mm in diameter and 11.2 mm thick, and water-resistant to 30 meters. Seiko provided more than 1,200 units of various types of stopwatches for the Olympic timers, and to commemorate the event, also issued a commercial version of its wristwatch chronograph, which had a monopusher system. Its story begins with the 1964 Olympic games, held in Tokyo, for which Seiko was the official timekeeper. With all of its previous accomplishments, it is not surprising that Seiko was also responsible for creating Japan’s first chronograph watch. The Seiko Crown Chronograph was inspired by the 1964 Tokyo Olympics. At first, the need to import components meant that production was slow - just 30 to 50 pieces per day - but by 1910, Seikosha had managed to produce its own balance springs and by 1913, its own enamel dials. The Laurel had a silver case, 29.6 mm in diameter, a porcelain enamel dial, and a 12-ligne movement. Hence the debut of the Laurel in 1913, just 11 years after the first Hattori wall clocks. Hattori quickly recognized the growing worldwide popularity of the wristwatch and predicted that the demand for wristwatches would shortly outpace that for pocketwatches. The English name “Timekeeper” was a product of Hattori’s shrewd business sense, as he realized that such a name would expand future export possibilities for the product. The 54.9-mm silver case was made in Japan, but most of the 22- ligne movement was imported from Switzerland. After several years of producing high-quality wall clocks, Seikosha released its first pocketwatch, called simply the Timekeeper, in 1895. He was only 31 when he partnered with an engineer named Tsuruhiko Yoshikawa to set up the Seikosha watch factory, forerunner of today’s Seiko, in 1892. Hattori watch and clock shop in Tokyo’s Kyobashi district and began building and repairing watches and clocks. Seiko founder Kintaro Hattori was only 21 years old when he opened the K.
