Rolex Chronograph 9162

Reference 9162 belongs to the Tudor brand, a subsidiary of Rolex. Nicknamed the “Monte Carlo,” it was produced in the 1970s and is powered by the manual-wind Valjoux Caliber 234. This high-performance movement is a column-wheel chronograph with a semi-instantaneous date and a frequency of 21,600 vph. The watch is defined by its 40mm “Big Block” style case and its exotic, multi-colored dial with orange accents. Its significance is its bold 1970s design and mechanically sophisticated movement.
