Consigned by the family of the original owner, this incredible and rare Rolex Beta-21 'Texano' model is numbered 001, signifying that is was the first production model from the fabled line of early quartz watches.
Reference 5100
Rolex reference 5100 is a historic milestone in the development of the quartz watch. It was launched on the 5th of June, 1970, and Rolex had greatly underestimated the demand for the model. The initial pilot series production was completely sold out prior to delivery.
Reference 5100 was the first Rolex to have a sapphire crystal and a seconds hand being run by a pallet wheel to give a true 'sweep' center seconds unlike modern quartz movements. It was also a revolutionary new case design being more angular in its shape than the standard Oyster case.
Powered by the Beta-21 movement, a 13-jewel, 8khz quartz module first seen in prototype form in 1967, a year later in 1968, it was agreed by 20 Swiss watch houses to produce 6,000 of these movements. In 1969, a few hundred of the Beta-21 watches were released at Basel World. The revolutionary caliber was accurate to 5-seconds per month, a far superior accuracy of timing than any mechanical watch at the time. The design for the Beta-21 watch was a triumph and very characteristic of the era - a generally thick, angular, even chunky case (partly out of necessity as the first generation of quartz movements were comparatively large).
In 1972, Rolex left the CEH (Centre Electronique Horloger) to go on and develop their own in-house quartz movements which were later named the 'Oysterquartz' models.
