Orient Grand Prix Swimmer 100 T19420





The rand Prix Swimmer 100 T19420 was Orient's response to the prevalent superstitious belief of "More jewels, more value" during its era which led to the creation of this innovative watch.


While many of the jewels serve a decorative purpose, this particular reference, introduced as the "Swimmer" model, aimed for excellence with its claim to possess the "strongest waterproof case," boasting water resistance up to 10 ATM.


The primary allure lies in the intricate incorporation of 100 jewels and the robust case exudes durability, featuring exceptionally sturdy glass. Each facet of the case is meticulously polished, and the screw-down crown, accompanied by guards, adds a touch of functionality. The dial boasts a radially shiny silver design that has developed a unique salmon patina over time, while the intricately carved indexes and logo enhance its aesthetic appeal. The jubilee bracelet adds a sublime touch, and the caseback stands out with a golden medallion bearing an engraved Pegasus.



Preserved in pristine deadstock condition, this exemplifies Orient's unwavering commitment to excellence.


The watch currently runs flawlessly and will be sold as is. Please let us know if you wish to service it.
