Description

This is one of the ultra rare model 1630 Two tone Oyster Perpetual Datejust, case number 455327XX dating it to 1978; making this one of the first sapphire glass automatics from Rolex.

Made in tiny quantities, in order to use up the remaining 15XX movements at a time when the rest of the Datejusts had already switched to the new 3035; it is believed that less than 1,000 of these were ever produced. As far as we can tell the 1630 was only ever sold in the US, note the use of 14ct gold on both the bracelet and bezel, shown by the 14 stamp in the bracelet clasp.

When new these watches were 15% less expensive than the equivalent Datejust on a Jubilee two tone bracelet; which, in turn, was less expensive than the newly introduced two tone Oysterquartz

The case is the same as the subsequently introduced Oysterquartz, being a much more solid and angular style than the classic Datejust style. It is (along with the Oysterquartz) the only Oyster ever designed to include an integral band and as such can not be worn with a leather strap. The bracelet is unique to this model, the similar looking Oysterquartz two tone bracelet has only two gold links, unlike this bracelet which has three gold centre links. What makes this particular watch very special is that the case and bracelet retains almost all of the sharp edges and chamfers which are a feature of this model (and the Oysterquartz) but which are normally worn down by shirt cuffs and inexperienced polishers. I never like to say that a watch is unpolished, unless I have owned it from new; but in this case I have no hesitation in declaring this case as unpolished; it is impossible to get this combination of brushed and polished finishes whilst retaining all the sharp edges.

The movement is the 1570, with kif flector shock protection, 26 jewels and is adjusted to 5 positions and temperatures. Note that the Rolex catalogue shown is incorrect; the watch does NOT have 30 jewels, but as every other current Datejust did have 30 jewels, the person who compiled the catalogue jumped to an erroneous assumption.

The dial is a unique one for this model with the minute track on a separate inner sloping track. The gilt dial has applied diamond cut gold batons; the hands are gold batons with luminous inserts. The champagne dial is utterly unmarked.

The watch was serviced by my Rolex authorised watchmaker who fitted a brand new sapphire glass, case tube and winding crown
