Our Cyclops lens. Introduced in 1953 to enhance the legibility of the date, this curved lens, set on the crystal at 3 o’clock, above the window, is one of our most emblematic features. It has been continuously improved, from its composition to its shape, to achieve utmost efficiency. Today, it is made from a virtually scratchproof sapphire crystal and benefits from a double anti-reflective coating. This lens immediately catches the eye, bringing the date into clear focus at a single glance. Disc
