This timepiece is known for its uncommon pulsation scale. More typical are Cartier’s pocket watch chronographs with an external 60-second calibration. All functions, such as starting, stopping, and resetting the hand to zero, are activated by the winding crown. The high-quality movement features 29 jewels and has undergone testing in 8 positions. It bears the signature “European Watch and Clock Co., Inc.” a collaboration between LeCoultre (later Jaeger-LeCoultre) and Cartier, established in 1919 to produce exclusive mechanisms for Cartier wristwatches.
