Model Reference
Datejust reference 1603 is one of the earliest Rolex watches that came out sometime in 1959, with its manufacturing running until the end of the 1970s. The time span is too long for the reference to remain unchanged. Some details varied during these decades and depending on when it was made, a watch could reveal plenty of information about itself.
It is recommended to determine the manufacturing date when buying a Rolex watch from the vintage collection of the 1603 reference. Watches manufactured at different times could have identical reference numbers, but some period-specific features would differ.
It doesn't take much effort to notice what distinguishes a 1603 from most of the other Vintage Datejust watches out there. An engine turned stainless steel bezel surrounds the dial, creating an entirely different look for the watch than that of the standard fluted bezel Datejust.
The rest is all classic Rolex design of the era. An Oyster case measures at 36mm across, while the acrylic crystal covers the dial, and the Cyclops magnifies the date window at the three o'clock position. There were also a variety of dials available, including silver, blue, black, grey, and white. Most 1603 watches will be found on a Jubilee bracelet, but configurations may vary among individual pieces.
Inside the dial is a Rolex 15xx series automatic movement. The early 1603 watches are associated with the Calibre 1565, while later 1603's use the Calibre 1575. There is no instant set date feature, so to change the date, the hands must go through midnight.
Some time spent with the 1603 will reveal its age in all the right ways, despite the fact that this watch predated the use of sapphire crystals and quick-set date windows common to modern Day-Dates. This historical link to such an iconic Rolex, however, is largely what makes the 1603 reference so appealing.
A single feature or specification of this 1603 watch alone cannot define it, however, due to the many iterations it went through over nearly two decades of production in terms of dial, hour markers, luminous materials and other minute details. The search for the correct 1603 therefore may depend less on the reference and more on the specific watch itself.
