Quick facts:Watch: Rolex ref. 6062 "Stelline"Produced: Briefly, starting around 1950Case: 36mm Oyster, screw-down casebackMovement: Automatic calibre 9¾Complications: Triple calendar + moon phaseTop auction price: $6.2 million (black-dial, diamond-indexed example, 2025)A Watch From Before Rolex Became "Rolex"Long before the Submariner, GMT-Master, and Daytona cemented Rolex’s reputation as a watchmaking powerhouse, the brand introduced a series of elegant and sophisticated dress watches that featured intricate mechanical calendars and other horological complications. The 6062 is among the few references in this category, alongside the 8171, to utilise an automatic triple calendar and a moonphase aperture.The dial does more than show the time:Two small windows near 12 o'clock display the day and monthA central pointer hand tracks the date around the case's outer edgeA moon phase indicator sits at 6 o'clockOn "Stelline" dials, standard hour markers are replaced with tiny stars, Italian for "little stars", giving the watch both its nickname and its distinct lookThere's also a historical footnote collectors love: years before "Cosmograph" became permanently attached to the Daytona, Rolex reportedly used that same term in period advertising for the 6062.

The reason vintage timepieces are gaining ground as alternative assets is that they represent a “controlled supply". The houses don’t produce more (Rolex), and fewer pieces retain their original dial over time. These factors, coupled with collectors’ demand, drive prices up for certain watches, making them investment items, with the most prominent representing a peak of affluence, fetching millions at auction, and dominating the financial news.What Buyers Can Learn From ItYou don't need eight figures to apply the lesson. What typically separates a watch that holds its value from one that doesn't comes down to the following:
