ETERNA – MILESTONES IN HOROLOGY. What would the world of watches be without Eterna? Probably much less eclectic. But certainly lacking the excitement of many groundbreaking developments. There is plenty of evidence to back this statement. For starters, Eterna created the ball-bearing-mounted rotor for self-winding movements. Its five tiny spheres, which also symbolise the Eterna brand, are the undisputed global standard in automatic wristwatches. Then, there was the world’s very first alarm wristwatch, the smallest self-winding movement with a gold rotor, the thinnest quartz wristwatch of all times with a mere 0.98 mm, the smallest quartz movement for ladies’ watches, and on and on. For connoisseurs of Swiss quality timepieces, all these accomplishments transformed the name Eterna into a genuine legend. And while many other watchmaking pioneers have meanwhile silently fallen into oblivion, we keep renewing ourselves. We can draw vital forces from our history, and we remain committed to the mission of preserving a great horological tradition.
