In outstanding original condition, this reference 3525 is among the most appealing and attractive examples of this model to be offered at auction in recent years. Its superb dial impresses with an extremely beautiful and warm salmon tone, free of any cosmetic enhancements. The hard enamel numerals and scales are full, the colours of the black tachymetre and the blue telemetre scales strong and vibrant.
From the early production of the reference it features the reference and serial number to the outside of the case back as opposed to between the lugs as found in later models. The case shows excellent proportions, the numbers are crisp and clearly readable, the original Oyster Patent crown is still present.
Reference 3525, one of the manufacturer’s first “Oyster” chronograph wristwatches, was produced between 1939 and 1945, and was available in a variety of metals. It is affectionately nick-named “monoblocco” by Italian collectors, referring to the fact that with the exception of the case back the entire case consists of one block including bezel and lugs.
Different versions in regard to case material and dial layout including a very similar watch are illustrated in: 100 Superlative Rolex Watches, John Goldberger, pp. 96-107, other examples also in: I Cronografi Rolex - La Leggenda, Pucci Papaleo Editore, pp. 162-192.
