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.
Some of the topics covered in this caliber listing:
Accuracy:
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)
Microbrands:
The caliber 9015 is featured in many microbrand watches such as the Marc & Sons Pilot watch. Here is what they have to say about it:
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.
Replacement Prices:
