The functions of this Oyster Perpetual Datejust watch are hours, minutes, seconds, and date. These functions are cleverly set out on a black dial with obelisque hour and minute hands, a central seconds hand, luminescent index hour markers, a date display at 3 o'clock, and a Rolex logo below 12 o'clock. The watch's comfortable and durable oyster bracelet is made of polished stainless steel and 18K white gold while the case is made of polished stainless steel. The round, diamond-studded bezel is made of 18K white gold.
