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.
