Rolex automatic Reference 1530. Introduced in 1975. Rolex created the case design for Oysterquartz, which is reminiscent of Royal Oak and Nautilus, before the development of the quartz movement was finished two years later. Therefore Rolex encased some of the cases around (and at most) 1,500 units, up until the quartz movement was ready in 1977.
The dial of the 1530 was originally silver, although the patina has created more of yellow tone over the years. Additionally, the angular minute scale with the offset dial is somewhat more dynamic than the dials seen on the later Oysterquartz models.
The dial of this Rolex Oyster Ref. 1530 is in exceptionally good condition, has a brushed silver finish, applied index markers, with classic 'ROLEX’ and ‘OYSTER PERPETUAL DATE' text referenced on it. The distinctive, angular case is sharply beveled, with diameter of 36mm. The large rehaut (with applied lume dots), conceals the depth at which the mechanical movement sits in the case, having originally been designed to house a thicker quartz calibre. It has its Rolex crown and comes equipped with its original, integrated Rolex bracelet and clasp (ref. 96660).
Inside the watch, it houses Rolex’s calibre 1570 ‘Officially Certified Superlative Chronometer’ grade automatic movement. The mechanism features a lever escapement, 26 jewels, mono-metallic balance and KIF shock-absorber, beating at a rate of 19,800 BPH. A distinctive characteristic of Rolex’s Cal. 1570 is the use of brightly-coloured reverser-gears in the automatic winding module. The unique colouration is created using Teflon, a branded form of Polytetrafluoroethylene, as a coating, resulting in far less friction.
