The Rolex Datejust ref. 1603 is a true vintage classic, highly appreciated by enthusiasts looking for a discreet yet characterful watch.
Compared to the more famous ref. 1601, it stands out for its steel engine-turned bezel, which gives it a more understated and less flashy appearance.
This 1977 example is particularly charming. Its main feature is the rare original black tritium dial, beautifully aged with large creamy tritium plots. The overall condition is excellent — the dial, case, bezel, bracelet, and movement are all exceptionally well preserved.
All components are period-correct: T Swiss T dial with tritium indexes and hands, steel engine-turned bezel, caliber 1570 movement, caseback signed 1601, and bracelet 78360 V6 with 558 end links.
A truly beautiful watch — elegant, timeless, and perfect for everyday wear.
