Ebauches SA Logos
Ebauches SA adopted a shield logo by 1939, with each affiliated company placing their own logo in the shield. Grail Watch has identified 28 logos in total, 17 of which are shown on the Europa Star table below.
Most of the Ebauches SA shield logos are somewhat obvious, being the initial of the company or factory location, but others are a little more obscure. Fabriques d’Ebauches Bernoises consisted of factories in Cortébert, Soncéboz, Villeret, Court, and Porrentruy, but it takes the “AV” from “Aurore-Villeret.” Vénus SA uses a star, its historic symbol/ Valjoux SA uses the “R” in reference to the Reymond brothers who founded the company. “T” for “Tavannes” overlaps the “U” for Unitas.
Some of the rarer shield logos include the radio wave used by Oscilloquartz, which is not seen in the table below. Other later logos include EEM, ESA, INT, MPG, ST, and SWG. Ebauches SA also used a dove logo to represent the whole company.
ETA, the successor to Ebauches SA, retains their original logo, which incorporates a round representation of the company’s initials. This pre-dates Ebauches SA, being first seen in 1925. Previously, ETA used block letters, sometimes with an oval around them.
The modern ETA has not retained the various factory logos used by their predecessor companies, however. The major ebauche factories in Fontainemelon, Grenchen, Moutier, and Bettlach all use bear the ETA name. But the continued presence of the traditional shield suggests this long history.
Ebauches SA Timeline
