Vintage Eterna regularly punches way above its weight class, this Kontiki 20 is the perfect example of that value. THE FULL STORY Eterna started its life as a movement manufacture named “Dr. Girard & Schild,” established by Josef Girard and Urs Schild in 1856. The Eterna name didn’t appear on the dial of the company’s watches until 1889. Eterna was the first company to bring to market a wristwatch with an alarm function in 1914 (patented in 1908). Eterna was also a proponent of the introduction of self-winding movements, with the Eterna-matic series, starting in 1948. The Eterna-matic was different from other automatic calibers of the time, as its construction featured a five ball-bearing mounted rotor system to reduce the level of friction, a design that eventually set a Swiss watch industry standard. Eterna’s logo is even a depiction of the five ball-bearings. Featuring a five-ball-bearing rotor-equipped Eterna-matic movement inside, the Kontiki 20 we have here is a downright gorgeous watch. Easily on par with Rolexes from the era, this all original powerhouse comes with the original, rare signed bracelet crafted by none other than Gay Freres.
