We are proud to offer this Heuer Carrera in pristine, mint condition. This Carrera dates back to the 1960s and carries the reference 3647D. The "D" in this reference stands for Decimal—a rare variation with a unique blue, two-tone scale. Unlike traditional scales, the Decimal scale divides a minute into 100 "parts" instead of 60 seconds. In this scientific decimal format, one decimal "second" equates to 0.864 seconds. The dial is in flawless, mint condition.
Inside the sharp, stainless steel case with strong lugs lies the Valjoux 92 caliber, a recently serviced movement with a signed bridge. The crown is signed, and as a final touch, the original stock sticker remains on the case back. This watch comes with original warranty papers, left blank, we acquired the watch from an old Heuer retailer.
