The Miyota caliber 9015 is a 24 jewel automatic movement. It is made in Japan and was first introduced in 2009. This movement is found in many new microbrand watches because it is easily obtainable, has a desirable hacking function, and considered a workhorse movement.
Citizen (Miyota) claims the accuracy of the caliber 9015 to be within -10~30 seconds per day.
The mainspring becomes fully winded by rotating the ratchet wheel 7.5 times (turning the crown 40 times)
The caliber 9015, which was presented for the first time in 2009, is a revolutionary development of the 8215 caliber. Equipped with a ball bearing rotor, a second stop and a date with a quick-change circuit, this new plant works very precisely with 28,800 half oscillations per hour. The range deviation is indicated as -10 to +30 seconds per day. According to experience, however, the work runs much more precisely, in some cases with a deviation in the single-digit second range. Furthermore, the movement has a shock absorber, a Swiss anchoring inhibitor and a manual hoist. The reserve is 42 hours. The movement is a technical masterpiece due to its low overall height of only 3.9 mm.
