Originally released to the market in 1928, the Rolex Prince, or "Doctor’s Watch", was an unbelievably accurate wristwatch. Often fitted with a chronometer movement, the model featured a subsidiary seconds register below the hours and minutes section of the dial, enabling a doctor to time pulses and respiration, hence its moniker. Rolex capitalized on this concept during the period, marketing the watch to professionals in the medical industry. The watch absolutely captures the zeitgeist of the 1920s, with its elegant, stepped case and deco-style dial composition.
