Taking a closer look at the Holy Grail Zenith Movement Rolex Daytona with @robertinothejeweler. From 1980-1999 Rolex purchased the Zenith movement from Zenith and placed it in the Rolex Daytona, 16520.
Today, this model is highly sought after by many collectors as the zenith movement demands a higher price and is more limited in supply. Because of its 70s look, some call this model a neo vintage (though it’s not really a Vintage Rolex).
The movement was originally delivered with a date function by Zenith, which was removed by Rolex before putting it in their Daytona model. You can tell the difference between a Zenith Daytona from a non-Zenith Daytona, by simply checking if the second hand is in the 9 o’clock position. The secondhand is at the 9 o’clock on Zenith movement Daytona’s while a non-Zenith is at the 6 o’clock.
