It MIGHT pass the pressure test now, but remember sapphire crystal is extremely hard yet brittle. If the fitting is not proper, it can shatter or crack (then shutter) later. Unlike acrylic, there is no give .
You will need two different grades. Start with something like 2.5-3.0 micron to remove the scratch but that will leave the area a tad hazy so you need to go over it a second time with a final polish 0.5-1.0 micron. Take some pauses if/when the crystal gets real warm.For the Rolex Deepsea, this means 3,900 metres (12,800 feet) below the surface, where there is immense pressure, equivalent to approximately three tonnes, on the sapphire crystal.

Is this an auto send back for some of you or do you keep it until general service or a more significant ding?
