A Rolex Oyster Perpetual Day Date model, often referred to as the "President", in solid eighteen carat yellow gold.  This is an exceptional, pristine, example of the third reference of this iconic, and arguably game changing model for Rolex.  The watch was first introduced into the Rolex line up under the reference 6511 in 1956, and a year later was re-modeled as the 6611 and featured the Rolex calibre 1055 movement.  This model ran until 1959 when the 1803 reference was introduced with a new movement again.  This time the 1555 calibre.  This 1803 model is fitted with the updated 1556 calibre movement which was initially launched by Rolex in 1965.  This example is in excellent condition, with the movement and case and in superb, original condition.  The case back still has the Rolex case back sticker still in tact.  The rare black, almost charcoal, dial with gold writing is untouched, and shows no sign of wear or damage and has all of the lume plots still in tact.  The day of the week wheel in this example is written in Spanish, which is less common.  The serial number of this watch is 3590XXX which dates it to circa 1972.  The hallmark on the case lug is still crisp, which illustrates that the case has received very little polishing over the years, highlighting that this example was worn very infrequently.  The solid eighteen carat Rolex "President" bracelet is in exceptional condition.  There is little to no wear in it, no 'sag'.  It also comes with one extra link.  The watch comes with a Foundwell one year warranty.
