Signed Rolex, Oyster Perpetual, Datejust, ref. 1601, case no. 3'822'712, circa 1974

A very attractive and classic combination of rich blue lapis lazuli and cool white gold, only a small number were produced of the reference 1601 white gold Rolex Datejust with lapis lazuli dial.
Over the years Rolex has created many different dial designs with a variety of materials. Rolex has and continues to experiment with many different hard-stones. Due to the fragile nature of the stone many of these hard-stone dials break during production, they are therefore costly and subsequently highly sought after by collectors.
