Seiko 7A28 7020 Quartz Chronograph

 The Seiko 7A28-7020 has a white dial, three subdials and steel case and steel bracelet. Note that a similar model is available with day-date (7A38), but Bond wears the one without the day-date. The same model can still be found, also in gold.  

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. Just eleven years later, in 1892, he established the 'Seikosha' factory.

In the 1960's, Seiko announced itself on the international sports timing stage with a whole new generation of high-precision equipment that was enthusiastically endorsed by many international sports federations and used to capture elapsed time at many of the world's leading sports events. Central to this success was a range of stopwatches that incorporated Seiko's innovative "heart-shaped cam" mechanism, a feature which delivered a level of precision once thought unachievable by manual sports timing devices. Then, in 1969, Seiko introduced the Seiko Speedtimer with the innovative Caliber 6139. It was the world's first automatic chronograph with a column wheel and vertical clutch, two devices that delivered real improvements in the measurement of elapsed time in a wristwatch and are still a prerequisite in high functionality chronographs.
