Description

Innovative and exceedingly rare Rolex ‘waterproof’ wrist watch.

A brief history explanation about this Rolex ‘Hermetic/Submarine/Aqua’;

The Submarine, also known as the Hermetic, was an early attempt by Rolex to create a waterproof wristwatch. Throughout the First World War, Rolex used two-piece cases made by Dennison and Borgel. These watches saw soldiers through the mud and the mire of the battlefield, but there was still room for improvement, particularly when Rolex saw new frontiers: the tropics. The beginning of a new Rolex watch case design was born.

The climates of India and East Asia, where Rolex’s most avid clients lived, necessitated a watch that was both dustproof and waterproof. Cases made by Dennison and Borgel were certainly dustproof, and shielded the sensitive movements from the dusty conditions of the battlefield. However, they proved less than adept at keeping moisture out.

In January 1921 Jean Finger, a watch case maker of Longeau, Berne, Switzerland, was granted Swiss patent number CH 89276 for a “ Montre à remontoire avec boitier protecteur” literally “a stem winding watch with a protective box”

This design of waterproof watch had the virtue of simplicity, in fact it was brutally simple; the watch was placed inside a larger case with a screw-down bezel which formed an hermetic seal around the watch within. To wind the watch or set the hands the outer bezel was unscrewed and the movement flipped out on a hinge allowing the hands to be set and the watch mainspring wound by a conventional unsealed crown.

Wilsdorf must have liked the design of Jean Finger’s hermetic case and bought some rights to the patent. He applied for a patent on exactly the same case design in Britain on 26 May 1922, which was granted British patent number GB 197208 “Improvements in and Relating to Watches”.

Although the hermetic case would soon be supplanted by the now-iconic Oyster case, which was patented in 1926, the Rolex Hermetic is an interesting artifact of an era when watchmaking was entering a new frontier. Mankind was just testing the boundaries of the known world, with intrepid explorers just venturing beneath the surface of the ocean; as one of Rolex’s first waterproof wristwatches, the Submarine paved the way for the Submariner. And with Submariners from the 1950s and 1960s becoming so popular, its aquatic ancestor deserves a spot in any serious Rolex watch collection.
