The monobloc middle case is secured by a screw-down case back and a screw-down Twinlock winding crown, offering waterproofness to 100 metres. A fluted bezel frames the scratch-resistant sapphire crystal, which features a Cyclops lens positioned over the date window.

Completing the presentation is an 18 kt white gold diamond-set President bracelet secured by a concealed folding Crownclasp, lending the piece its unmistakable formal character.
