Cal. FP 610 (also called Cal. FP 6.10) is a compact and thin movement. When it was released in 1993 it had the smallest combination of diameter (15.3 mm) and thickness (2.1 mm) of any movement. It is closely related to the Cal. 615 automatic movement.
As an ultra-thin movement, it uses a flat hairspring.
