VINTAGE GOLDEN ETERNA-MATIC WRIST WATCH
This is a Swiss Eterna-Matic men's wirst watch. The watch case, a typical product of the mid 20th century
and made in France is entirely made of 18K gold.
It is embellished with black leather strap.
Some background information on Eterna:
Eterna S.A. began life in 1856 in Grenchen, a small town in the northwest of Switzerland near other
famous watch-making towns such as Biel, La Chaux de-Fonds and Le Locle. The original name
of the company was U. Schild, after its co-founder schoolteacher Urs Schild, who set up the company
with doctor Josef Girard.
In 1906 the name of the company changed to 'Eterna-Werke', and in 1932 it divided into 'Eterna
S.A.' which specialised in precision movements, and 'ETA S.A.' which concentrated on making raw movements.
In 1948 Eterna produced their first rotor automatic, the 'Eterna·matic', in the ladies' cal. 1198. The outstanding
innovation in this calibre was the mounting of the rotor on 5 ball bearings, each of 0.65mm diameter.
This arrangement produced a particularly low friction and rugged mounting for the rotor,
which together with a low friction springless double click wheel allowed bi-directional winding.
A similar layout was used in the first men's rotor movement, the cal. 1248 of 1950. The double
click wheel was later replaced (1956) by two thin beryllium click wheels side by side, which
increased transmission capability and allowed a considerable reduction in movement height.
So successful was the basic design of this movement, that all Eterna automatic movements
ever since have incorporated the 5 ball bearings and have been called 'Eterna·matic'.
