The Citizen 4103 watch movement features Seiko-Diafix combined settings for the escape wheel and 3rd wheel, a ball-bearing rotor, and a sophisticated excenter self-winding mechanism with just one gear stage. It is an automatic movement with no manual wind capability, a sweep second hand, a date function that is set by a pusher at 2 o'clock, and a power reserve display. This movement was utilized in watches produced around 2003.
