Rolex Chronograph Single Button Chronograph

Rolex Single-Button Chronograph housed in a 9K yellow gold case featuring distinct downturned, slender lugs and a smooth bezel. Its matte champagne dial displays a twin-register chronograph layout with two sub-dials positioned at 3 and 9 o'clock, paired with a central heated blue-steel hand configuration. The dial is characterized by an elegant outer pulsometer scale marked "GRADUE POUR 30 PULSATIONS" sweeping along the top left quadrant, a black printed Rolex signature, and clean Arabic numerals for the 12, 2, 6, and 10 o'clock positions alongside stick hour markers. Uniquely, the case profile includes a distinctively oversized fluted crown and a single prominent oval chronograph pusher situated at the 2 o'clock position to handle start, stop, and reset functions. The historic watch is elegantly mounted on a classic stitched black leather strap.
