  • Additional info – DD Sapphire crystal upgrade from the OEM SD hardlex crystal. Double Dome so no optical dial distortion even at acute viewing angle – looks superb – one of my top selling sapphires. Superb upgrade to Sapphire for the Mini/Baby Turtle and at the same time getting rid of the unsightly cyclops date magnifier.
