Citizen Grand Classic (Ref: NB3016-05E) (Add your watch to the comments below…)

Citizen caliber 9184 is an automatic watch movement with a 24 hour hand and a power reserve indicator. This movement is made in Japan with 26 jewels and a high-beat frequency of 4 Hz (28,800 beats per hour).

“9184” is the caliber designation used for movements branded for use in Citizen watches. For non-Citizen watches, this movement is sold as cal. 9134 by Miyota – making it a member of the Miyota 9 series or 9000/9100 family of premium automatic movements.

Citizen watches with the 9184 have been available since at least 8/2017, but the Miyota version of this movement is listed as discontinued as of this post.

Power Reserve:

The 9184 has a power reserve of about 40 hours on a full wind. It takes about 40 turns of the crown to reach full power reserve. This particular movement has a power reserve indicator complication, allowing the wearer to see how much energy is remaining in the spring before the watch stops running.

I have one, and gets discalibrated easily. the balance wheel gets disadjusted very easy with a little bump from the hand. Do you know which balance wheel might be used to replace the one that comes with the 9184?
I mean, a bump with my hand and the watch gains 50 sec/day, another bump and the stem moves again and gets worst or start losing 30 sec/day. I haver a timegrapher and this thing is not normal. I observed the stem leavers move easily with bumps…
