At a classic 38.5 mm in diameter, the case boasts a fine satinized finish and exudes outstanding, sophisticated functionality.
Particularly noteworthy is not only the guilloché, silver 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.
