Part of the Miyota Cal. 9000 family, Cal. 9039 is a central seconds automatic movement. It is quite similar to the Cal. 9015 but without the date wheel.
Production of Cal. 9039 began in 2018 and continues as of 2019.
The movement can be manually wound with the crown in position 1. Rotate the crown clockwise to wind the mainspring.
The time is set with the crown in second position (pulled all the way out). Rotate the crown clockwise to advance the minute and hour hands and counter-clockwise to turn them backward.
