Rolex Oyster Perpetual 41 mm

The Rolex Oyster Perpetual 41 mm, reference 134300-0009, is made of steel and carries a medium blue dial. The case measures 41 mm across and 11.7 mm thick, with a domed bezel finishing the profile. Sapphire crystal protects the dial, and the hands and indices carry luminous treatment for legibility. Inside is the calibre 3230, a self-winding movement built by Rolex with a power reserve of around 70 hours. It is certified as a chronometer and shows the time with a central seconds hand. The steel Oyster bracelet fastens with a folding Oysterclasp that includes an Easylink comfort extension for quick sizing. The screw-down Twinlock crown helps hold the case to its 100 metre water resistance rating.
