The ETA (formerly Valjoux) 7750 automatic chronograph movement is a robust and reliable cam-operated chronograph movement. It has spawned a family of chronograph and time-only movements and is used as a base for many complications and third-party watch movements.
Introduced in 1974, the Valjoux 7750 was soon retired but returned in the 1980s. It has come to dominate the industry and remains popular today.
When the 7750 was re-introduced in 1985, a number of additional related movements were also created, including the 7751 and hand-winding versions. The line was refreshed in the early 2000s, with the hand-winding variants retired and new 7753 and 7754 added.
ETA later used the 7750 design for a family of larger Valgranges-branded movements. Many of these are time-only, though ETA also makes retrograde versions for Longines and a column wheel version for Omega.
The Sellita SW500 family is considered a clone of the ETA 7750.
