Most ETA movements use Mineral Glass.
Do you know if this is true of the ETA 2892-2 movement? If you do not know how could I find out? I have a watch with that movement that is ready to be cleaned, lubricated and recalibrated. If the watch is using mineral glass is the longevity of the movement any different than if it had lab created jewels? Thanks.
