The automatic movement is the same caliber 89801 as the earlier edition with 51 jewels and 68-hour power reserve. The sapphire-crystal, screw-down case back displays the beautiful Spitfire-form rotor that this line is known for. Additionally, the anti-reflective crystal is secured against displacement by drops in air pressure.
