This is the caliber 410, a 17 jewel movement that is 10.5 ligne or 23.7mm in diameter. Almost all parts will interchange with others in the 405-series. The only difference between the 410 and the 420 is the size; other wise it is fully interchangeable. These movements are always marked with the caliber number in the space next to the balance wheel and the cap jewel for the escape wheel.
