Does the 3186 movement use ceramic ball-bearings?
In the bezel and winding mechanism.

The new movement utilizes a ball bearing that is mounted to the movement as the oscillating weight. This is a change from a plain bearing. Not sure if it’s ceramic or steel.

Watches like the ceramic insert bezel GMT 116710 the bezel sits on 3 ball-bearings and a spring loaded click stop.And there is nothing ceramic in the manual winding mechanism on any Rolex watch.And the 3186 movement is a modified 3185 that has slightly improved second timezone setting but no big deal there.They have introduced a steel ball bearing rotor in the auto-wind mechanism in the 32 series movement instead of the sleeve bearing rotor on the 6 digit 31 series models.The last of the 16710 GMT could have a 3186 movement in the case but that will still use the older axle sleeve rotor auto winding.

I believe only the 32xx movements have the ball-bearing mounted winding rotor, besides the Daytona's 4130 which introduced it. I am not sure about the Sky-Dweller's movement.

As Bas mentioned, they are not ceramic ball-bearings.
