Made in 1970 with a production of only 999 pieces, the 5100 reference was the first quartz watch produced by Rolex, and at the same time it was the first model of the Maison featuring sapphire crystal and quick-set date.
It is powered by the Beta 21 calibre, the revolutionary movement which was the result of the collaboration between the Centre Electronique Horologer and a consortium of Swiss brands (including Patek Philippe, Omega, Jaeger-LeCoultre, Longines, IWC ...), which represented the most accurate quartz caliber in the world, accurate to 5 seconds per month.
To crown the debut of this watch, the Maison established the "Rolex Quartz Club", as well as a Golden Book where the exclusive owners of the model could place their signatures and have the privilege of a guided tour of the Rolex headquarters in Geneva. The 5100 had a very short but extensive commercial success, and all the pieces were sold even before reaching the market.
The watch included in this auction is in perfect condition, having been rarely used, and has just had a complete overhaul carried out in January 2019 by a well-known laboratory. With its limited edition number "15" it represents one of the very first specimens of the 5100 proposed at auction in recent years.
