拍品专文

The CEH-230 Beta 21 Prototype was an early experimental quartz movement developed by the Centre Electronique Horloger (CEH) in the 1960s as part of the Beta 21 project, Switzerland’s first major effort to create a commercially viable quartz watch. This prototype featured a large quartz oscillator and an electronic circuit to drive the stepper motor, setting it apart from traditional mechanical movements. Unlike the final Beta 21, which was adopted by brands like Omega, Rolex, Patek Philippe, Piaget and many more, the CEH-230 remained a test model and was never mass-produced. It is believed that only 10 prototypes were made, some featuring a calendar mechanism, while others did not.

The Centre Electronique Horloger (CEH), founded in 1962, was a Swiss research institute dedicated to advancing electronic watch technology. It played a key role in developing the Beta 21, introduced in 1969, in response to growing competition from Japanese and American quartz watches. Though innovative, the Beta 21 was soon overshadowed by more efficient designs like the Seiko Astron. The CEH was eventually absorbed into other Swiss institutions, but its contributions helped shape modern quartz technology and ensured the survival of Swiss watchmaking during the Quartz Crisis.
