Collectors prioritize this reference for its three-register layout and the inclusion of a tachymeter scale printed on the outer edge of the dial, which distinguishes it from the cleaner 2447N or 2447S models. The watch features a 36mm stainless steel case with sharp, angular lugs and is powered by the manual-wind Valjoux 72 movement, a caliber noted for its reliability and historical significance in mid-century chronographs. Current secondary market prices typically range from $12,000 to $20,000 depending on the condition of the dial and the sharpness of the case edges. A notable production detail is the transition from \"Swiss\" only dials to \"T Swiss\" markings, indicating the use of tritium. Early executions featuring \"eggshell\" white dials and thin tension rings are particularly sought after at auction.", "score": 200}]}
