The Miyota caliber 9019 is a 24 jewels 3-hand automatic movement based on the 9 series framework. Miyota categorized this caliber as part of the “Premium” line of automatic movements. This is an in-house (Citizen owns Miyota) movement, made in Japan.

Miyota 9019 VS 9015:

The caliber 9019 is basically a 9015 but with a lower clearance for the hands. It has the same thickness of 3.9mm, but the ability to install the hands closer to the dial allows for an overall thinner watch design. In measurement, the difference is 1,750μ vs 2,100μ.

These two calibers are so similar that Miyota doesn’t even bother to show an image of an actual 9019 in their catalog – they show the 9015 on the 9019 page.

Accuracy:

Miyota claims that the accuracy of the caliber 9019 averages between -10 and +30 seconds per day under normal temperatures and operating conditions.

Power Reserve:

To get the best accuracy and performance out of your 9019 powered watch, you will want to make sure your watch is fully wound. When manually winding the crown, it takes 40 winds to reach full power reserve. A full power reserve gives a running time of about 42 hours.

Setting the Time:

The 9019 has 3 crown positions: against the case (manual winding), pulled out one click (date setting mode), pulled out 2 clicks (time setting mode). Note: Miyota states that the date should not be set between 8:30PM to 2AM.
