The LeJour Jurvac Model 8706/66 featured an interesting and innovative design, featuring a vacuum-sealed case filled with argon gas, advertized as water resistant to 10ATM.  Intriguingly, these were referred to as diving watches, albeit without the common rotating bezel, signifying a diving watch. 

The vacuum-sealed, argon-filled case was designed to maintain positive inner-pressure, prevent leaking, and was made by the same manufacturer as Glycine’s Vacuum watches. Argon gas was used for its dry gas properties, which contain no humidity. Thus, no condensation can form inside the case due to temperature changes, and therefore no corrosion can result.

LeJour was a French brand founded in 1965, and it operated through the early 1980's, specializing in more affordable versions of watches nearly identical to Heuer and Porsche Design/Orfina offerings of the era - such as the "Poor Man's Heuer," Le Jour's popular Valjoux-powered chronograph, which was identical to the Pasadena save for the absence of the Heuer logo.
