The Sellita SW500 family is considered a clone of the ETA/Valjoux 7750 family, though there are many more variations from Sellita. Many parts are interchangeable between these movements.
Sellita makes a wide assortment of variations on the basic 7750 design. Movements ending in “0” feature a 30 minute chronograph counter, while those ending in “1” have a 15 minute counter. The monopusher “MP” movements have a separate pusher at 2:00 while the “MPC” movements have a pusher coaxial with the crown.
