The present prototype, bearing the serial number 761, is one of the most legendary and historic pieces in the world of Quartz watches. It is of exceptional importance both in the history of Rolex and in wider horology.
The Oysterquartz Perpetual Rolex Day-Date originated from the idea of 11 November 1987, when Rolex filed patent CH672222 with the Swiss Federal Patent Office in Bern. The patent describes a method of programming a wristwatch with a perpetual calendar operated only by the crown. Most of these ideas never make it past the prototype stage, let alone into production.
While the exterior design has no visible differences to its famous mass-produced predecessor with the 5055 calibre, the movement details are of great significance. One notable difference between the two calibres is the difference in sound: the 5055 has an audible ticking sound, while the 5355 is completely silent. In addition, the calibre 5355 uses stepping motors for the minute and second hands, which allows for a battery life of 10 years.
This example not only stands out from the few known models in this series but is also one of the few models with a fully functional movement. All adjustments can be made via the winding crown, so there is no need for an additional setting pin to activate additional pushers.
This fascinating and important wristwatch offers the collector the rare opportunity to possess an extremely rare Rolex that is not only technically impressive but also eminently wearable.
