Crafted from two distinct metals, the Tiffany Edition exemplifies the art of fusion. The combination creates a case that stands out in design while remaining impressively lightweight.

The sapphire crystal complements the case. It offers clarity and transparency while allowing the movement to appear as though it is floating within. The titanium elements are finished with a micro-blasted satin coating. It enhances the matte look and creates an effect that reflects light subtly, without overpowering the elegant design.
