Vintage 1964 Rolex Oyster Perpetual Datejust 1601 with the Sigma dial

The Rolex 1601 has become such an iconic collectors Rolex watch. Fitted with the esteemed Rolex automatic calibre 1560, the calibre 1560 was the second generation of the 1500 series. This movement was launched in 1959 and remained until 1965. Fitted with a 26 jewel automatic movement, it had a Rolex 7980 balance assembly with and a Bregeut free sprung hairspring and has a power reserve of 42 hours.

A brief history on the sigma dials:

The history behind sigma dials is a very interesting one which has now made watches with these dials highly sought after. The sigma dial is discreetly marked with the Greek letter sigma (Ó) on each end of the T SWISS T or SWISS at the bottom of the dial. From 1970, watch companies who were members of the l’Association pour la Promotion Industrielle de l’Or (APRIOR), such as Rolex, Patek Philippe, IWC, Omega and Vacheron & Constantin to name a few, produced dials with the sigma letter to notify that the hands and index markers are made in gold. This was used at a time when the Japanese “quartz revolution” started coming in, and sigma dials were produced for one main reason – to notify when gold parts were used on a watch, including the dial to subsequently add to both the financial and intrinsic value of a watch. An important and quite interesting point to note, is that the sigma dials can be found on watches that are made all in stainless steel ie case, band and bezel, but with a sigma dial, not the index markers and hands.
