FEF (Fabrique d'Ébauches de Fleurier) was a Swiss manufacturer of watch movements, known as ébauches, based in Fleurier, Switzerland. Established in the late 19th century, FEF became part of Ebauches SA in the early 1930s, a consortium that included other notable movement manufacturers like ETA, Unitas, and Valjoux.
FEF produced a variety of mechanical movements that were utilized by numerous watch brands. Here are two examples:
FEF 6662: A manually wound movement measuring 6¾ x 8 lignes, featuring 17 jewels, a beat rate of 21,600 vibrations per hour, and a power reserve of approximately 48 hours. This movement includes Incabloc shock protection and was listed in the Flume K3 catalog around 1972.
FEF 350: A 10½ ligne manual-wind movement with 17 jewels and a beat rate of 18,000 vibrations per hour. It features a monometallic screw balance and Incabloc shock protection. This caliber was documented in the Paulson catalog from 1950.
These movements were known for their reliability and were incorporated into watches by various brands, including Ebel and Paul Breguette.
