Deep confidence
The Oyster Perpetual Submariner Date in 18 kt yellow gold with a Cerachrom bezel insert in blue ceramic and a royal blue dial with large luminescent hour markers.
Royal blue dial
For legibility underwater

Hour markers in simple shapes – triangles, circles, rectangles – and broad hour and minute hands enable instant and reliable reading to prevent any risk of confusion underwater.
