The Seiko company was founded in 1881, when Kintarō Hattori opened a watch and jewelry shop in Tokyo. Eleven years later, in 1892, he founded the company Seikosha Co, where initially wall clocks were produced. Soon they were followed by pocket watches and watches with an alarm function. In 1913 Seiko (which means ‘precision’ in Japanese) manufactured its first wristwatch, and today the brand is well known for its inventions over the years.

Already in 1958 Seiko started with the developement of quartz movements, which let to the first commercial quartz wristwatch of the world in 1969, the Seiko Quartz Astron.

Seiko’s tradition in sports timing started at the 1964 Olympic Games in Tokyo, where they served as Official Timekeeper. Ever since the brand has been involved in many sports events, eg athletics, football and sailing. Probably beginning 1990’s the regatta caliber 8M35 was developed, with an adjustable countdown timer from 1 to 30 minutes, as well as preset timers for 5, 10 and 15 minutes.

With the launch of the Velatura series in 2007, Seiko rose to the challenge to build watches that perform on the open ocean, with a collection characterized by robustness, high functionality and durability. Also in 2007, Seiko was selected as the Watch Partner of the International 49er Class Association.

To mark the fourth year of their partnership, Seiko launced a new model in the Velatura collection, a standard chronograph housing with the caliber 7T62 Alarm movement. Not with a special countdown function, but with a coloured 5-10-15 minutes subdial.

The watch is available with either a stainless steel case with black hard coating and a polyurethane strap (ref. SNAE17) or a stainless steel case with blue hard coating and a stainless steel bracelet with three-fold slasp (ref. SNAE19).
