Origins and acquisition
Rayville-Blancpain denotes the historical Rayville business producing and trading Blancpain watches at Villeret. After Frédéric-Emile Blancpain’s 1932 death, Betty Fiechter and André Léal acquired the business; Blancpain’s 2018 account dates co-ownership to 7 July 1933.
Betty’s reproduced Christmas 1968 letter retrospectively dates acquisition and creation of Rayville SA to 1932, differing from the brand’s 1933 account. 123
People and production
Betty trained at Blancpain from 1912, became a co-owner with Léal, and led the enterprise after his 1939 death. Jean-Jacques Fiechter, Betty’s nephew through her brother Jacques-René, joined in 1950 and trained across production and administration.
For American customers, Rayville supplied movements with dials and hands in inner cases; customers fitted outer cases. 31
Products and group integration
The Ladybird appeared in 1956 with the small round R550 movement and a rear-positioned crown. The brand credits the Fiechter leadership period with the Fifty Fathoms and Ladybird programmes.
A 1930s Blancpain cocktail watch associated with Marilyn Monroe contains an FHF 59 movement bearing a Rayville Watch Co. inscription. Rayville-Blancpain joined SSIH in 1961 and served both its own watch business and the group’s movement needs. 1324
Leadership handover and later brand history
In her Christmas 1968 letter Betty handed full responsibility to Jean-Jacques while retaining an honorary presidency. Modern Blancpain’s timeline separates a 1982 acquisition by Jacques Piguet, a 1983 subsidiary and Biver appointment, and sale to SMH in 1992.
Blancpain attributes the Rayville name change to a Swiss family-name rule; no contemporary statute was independently verified here. 34
