I have been studying a lot into the watch businesses lately out of interest. One thing that has caught my attention is this.
Citizen owns Miyota and La Joux Perret. Also Frederique Constant was rumoured to be building its own Movement. Why do we still see them using ETA movements in Bulova, Frederique Constant and Alpina brands?
Festina Group owns Soprod but I think there are some watches that use movements/ complications from other movement maker. ( I might be wrong on this particular company).
A lot of Eterna Watches also use ETA movements even after Eterna has invested a lot in their own inhouse movements.
Why is this?
