About Eterna
Eterna has since 1856 manufactured high-quality mechanical timepieces born of traditional craftsmanship. Over its more than 150 years of existence, numerous major developments have emerged from the company’s workshops. At the 1904 Swiss National Exhibition in Bern, Eterna introduced the first wristwatch fitted with an alarm mechanism, a technical breakthrough which the company had patented in 1908. One important contribution was in the realm of automatic watches. Indeed, when Eterna unveiled the Eterna-Matic movement in 1948, it changed the way brands looked at automatic movements. The Eterna-Matic caliber essentially featured a ball-bearing mounted rotor system to reduce friction. Five strategically placed ball bearings reduced friction and resistance on the oscillating weight that winds the mainspring and increased the watch’s accuracy. Eterna was the first to utilize such a revolutionary system … a concept that later became implemented by other brands. The Eterna-Matic movement is still used in certain watches today.
