Five miniature ball bearings, each just 0.65 millimetres in diameter, changed the course of watchmaking. When the Eterna factory in Grenchen introduced the Eterna-Matic movement in 1948, its freely swinging rotor supported by those five tiny bearings set a new standard for automatic wristwatch construction. The innovation reduced friction so dramatically that it improved accuracy, durability, and power efficiency in one stroke. Nearly every automatic movement produced since owes something to that breakthrough, and the five balls became Eterna's corporate symbol, adopted as the company logo that same year.
Eterna's origins reach back to November 7, 1856, when physician Josef Girard and twenty-eight-year-old schoolteacher Urs Schild founded Dr. Girard and Schild in Grenchen, Canton Solothurn. The company initially manufactured unfinished movements (ebauches) for other watchmakers before producing its first complete watch around 1870 and presenting its first entirely in-house pocket watch in 1876. The firm rebranded as Eterna in 1905 and registered the trademark the following year.
Innovation came early and often. In 1908 Eterna patented the first alarm wristwatch, which entered production in 1914 and was presented at the Swiss National Exhibition in Bern. But it was the 1948 ball-bearing rotor that defined the company's place in horological history. The movement division that developed it eventually became ETA SA, now a Swatch Group subsidiary and the world's largest manufacturer of watch movements, supplying calibres to brands across the industry.
The KonTiki collection, introduced in 1958, became Eterna's signature sports watch line. Named for Thor Heyerdahl's legendary raft expedition, the KonTiki combined robust water resistance, triangular hour markers, and bold legibility into a tool watch that has been reinterpreted through Super KonTiki, KonTiki Diver, and Royal KonTiki variants across the decades.
Eterna is currently owned by Citychamp Watch and Jewellery Group, a Hong Kong-based company that acquired the brand in 2011.
On Auctionist, 135 Eterna items are indexed, with watches accounting for 111 pieces. Kaplans Auktioner in Stockholm handles the largest share (19 items), followed by various Stockholms Auktionsverk locations. Gold timepieces command the highest prices, with an 18-karat ladies' watch reaching SEK 18,055 and a single-button chronograph achieving SEK 17,000. Gold bracelet watches trade in the SEK 10,000-13,000 range. For watch collectors, Eterna represents a technically significant Swiss marque with a deep history that punches above its current market profile.
