Description

The date disc of the Datejust 31 is made of nickel silver – an alloy of copper, zinc and nickel – and sits on synthetic rubies to minimize friction and optimize the disc’s movement. The date change happens in a fraction of a second. The Cyclops lens, which magnifies the date, is made of virtually scratchproof sapphire and has a double anti-reflective coating for optimum legibility. #Rolex
