A bi metal Datejust is a timeless watch – they have been making them since 1945 to prove that point!  Model reference 1601


From the serial number between the lugs we can accurately date this watch to being made in 1971.  But the case back has a stamp for I72, meaning first quarter of 1972.  So the case was made in late 1971 but could not have been paired with the case back at the factory until early 1972.


The 1601 series Datejust ran from the late 1950’s to the late 1970’s, and has all the right styling features such as the stepped dial, open 6 and 9’s on the calendar and this model also has the iconic Jubilee bracelet – the watch was nearly called Jubilee not Datejust to celebrate the 40th anniversary of Rolex in 1945.  Inside the stainless case with 18k bezel is a calibre 1570, 26 jewel, automatic winding movement that is running well.  The acrylic glass is faultless, and has the correct 2.5x magnification cyclops over the date.  The dial is very good, with just the tiniest of marks.  The twinlock screwdown crown is signed with the correct crown and single line for a gold and steel case, and there is a small loss of the gold cap at the bottom of the crown.  The bracelet has 455B endlinks and is stamped 62473 on the Z Clasp, as well as OP12 – this indicates the bracelet is newer than the watch, which may be why there is not as much stretch as the older bracelets have.  The case has minor marks associated with age that would be removed with a polish, but we would advise people to keep it original and not polish the scuffs out.  The Datejust also looks great on leather, and thanks to the drilled lugs strap changes are easy.

One of many people who chose to wear a Datejust 1601 was Martin Luther King, and you can read about that here.
