Ruben & Sons MD3G

The MD3G is an automatic movement based on the Miyota 8215, assembled and finished in Switzerland by Ruben & Sons with a custom branded rotor. It operates at 21,600 VPH with a 42-hour power reserve and features center seconds, date, and day complications with Parashock shock protection. The movement is known for a characteristic "hesitating" second hand due to its indirect drive system, a trait inherited from the 8215 base. It is only available in finished timepieces, primarily from Gevril, and remains in production.
