Vintage Seiko Bell Matic 27 Jewels Day Date (846041)

In 1966, Seiko developed its own alarm watch, the BellMatic, containing either the 4005 or 4006 movement. The 4005 movement is significantly rarer than the 4006 since it was only used in 1968 and 1969. As is normal with Seiko movement numbers, a calibre with a number ending in 5 is the date only variety, while a calibre number ending in 6 is the day/date variety. Other than this difference, the movements are the same and we generally refer to the Bell-Matic movement as 400x when discussing both. 

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 Speed timer with the innovative Calibre 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.
