Notes

Ref. BA 196.005 was launched in 1970. Though intended to be worn on the left arm, the winding crown was at 9 because the watch does not require winding. The movement is so accurate that adjustment is required only when changing time zones or at the end of the month.

Caliber Beta 21
In 1962 the Centre Electronique Horloger was founded by a group of 21 Swiss watchmakers, including Rolex, Audemars Piguet, Omega, Piaget and Patek Philippe, to develop an electronic movement for wristwatches. The result was the Beta 21, a 13 jewel, 8Khz quartz module first seen as a prototype in 1967. In 1968 a consortium of Swiss watch manufacturers was created to mass-produce the Beta 21, in a truly collaborative effort. The CEH designed the module and produced the integrated circuit, Ebauches SA (now ETA) manufactured the mechanical parts of the movement as well as the quartz oscillator, and Omega produced the micro-motor driving the hands.
