At a classic 38.5 mm in diameter, the case boasts a fine satinised finish and exudes outstanding, sophisticated functionality. Particularly noteworthy is not only the guilloché, light-coloured copper electroplated dial, but also the highly curved sapphire crystal glass, which is ground out and carefully polished using a complex process involving an approximately 5 mm solid blank with five different curvature radii. This not only enhances the classic look of the glass, it also makes it stronger and more resilient than flat-ground glass. The anti-reflective coating on both sides facilitates accurate reading of the distinctively designed dial even under extreme lighting conditions. The transparent case back made of sapphire glass offers a fascinating insight into the fine mechanical movement, which has been decorated with an exquisite finish and blued screws.
