Miyota 9029

The Miyota 9029 is an automatic movement from the Japanese manufacturer Miyota, belonging to the 90/91 family. It measures 26mm in diameter, beats at 28,800 vph, and has a 42-hour power reserve with 24 jewels and Parashock shock protection. The movement features a two-hand display with no seconds hand and no date option, distinguished by an open-heart design showing the balance wheel at the 5:00 position. It shares its dimensions and jewel count with the more common 90S5, though the 9029 lacks the sweeping seconds hand.
