Ronda 9035-21

The Ronda 9035-21 is a manual winding movement manufactured by Ronda from 1965 to 1972. It features 17 jewels, KIF Protechoc shock protection, and a round profile. The movement includes a date complication with 21:30-24h change, an adjustable stud holder, and a calendar function, though it does not incorporate a second hand. Notable for its optional plastic bushings as an alternative to dial screws, the 9035-21 was discontinued in 1972.
