【comment】
Everyone knows that Rolex does not make complicated functions, and the ‘countdown’ of the Yacht-Master is one of the complicated functions that Rolex can count. Everyone knows that Rolex broke through the world with two movements and became the most deficient super brand in the ‘core’. However, have you ever thought that Rolex still has several patents for perpetual calendar technology? However, many quartz perpetual calendar technologies developed in response to the original quartz crisis have become a thing of the past, and let us focus our attention on the moon phase function included in this Datejust. Historically, Rolex with the moon phase function concentrated in just a few years from 1949 to 1953, and there are only a handful of configuration models: they are 8171 known by Italian collectors as ‘Padellone’ and were once called ‘COSMOGRAPH’ 6062, both are day, month, star calendar.
