The Miyota caliber 9039 is a 24 jewels automatic movement that was introduced to the market in 2018. As a member of the 9000 family of movements, this caliber is part of Miyota’s Premium Automatic line. It tells the time via a standard 3 hand display with no date option – it is a true no-date movement with no phantom crown position. This movement is made in Japan.
Some of the topics covered in this caliber listing:
9039 VS 9015:
There is a similar and more common Miyota caliber 9015. Both are 26mm in diameter, have 24 jewels, both beat at 28,800 vph, and have the same dial feet location. The two main differences between these movements are:
- The calendar complication
- The height of the hand stack
The 9039 is essentially a low-hand height version of the 9015.

The caliber 9039 is a no-date movement so the crown only has two positions: winding (position 1) and time adjusting (position 2). The set the time on your 9039 powered watch, pull the crown out one click to position 2. You may need to unscrew the crown if it is a divers style watch with a screw-down system.
Winding + Power Reserve:
Winding the movement 15-20 clockwise will start the movement. To fully wind the movement, turn the crown 40 times. The power reserve when the movement is fully wound is supposed to be more than 42 hours.
Miyota claims that the caliber 9039 offers accuracy of -10 ~ +30 seconds per day. This is measured within 10-60 minutes from a full wind via the crown.
Dial Feet Location:
At the time of this post, caliber 9039 replacement prices were found online in the range of $99.00 – $103.95 USD.
