This 18k yellow gold Rolex chronograph pocket watch, reference 2900, is a testament to the brand's mid-20th-century expertise in high-precision timekeeping. The timepiece features a 50mm diameter yellow gold case with an integrated single-pusher mechanism located within the winding crown.
It is powered by a manual-wind movement containing 17 jewels. The black lacquered dial is adorned with gilt graphics, including hour markers, numerals, and hands. It employs a classic two-register layout, featuring a 30-minute elapsed time recorder at 12 o’clock and a running seconds subsidiary dial at 6 o’clock. A gilt tachymetric scale calibrated on a “base 1000” surrounds the dial, designed for calculating average speeds over a distance of one kilometer.
The dial is signed “Rolex Genève” and carries the “Extra Precision” designation, reflecting the rigorous regulation standards of the period. The case, dial, and movement are all signed by the maker.
