Introduced in the mid 1930s the Rolex reference 2508 is a favorite amongst collectors due to its oversized case, flat bezel, and classic no frills design that is more in-line with those of two other historical Genevan brands: Patek Philippe and Vacheron Constantin. This reference existed in two different configurations, the first models with olive shaped pushers and larger case, the second generation coming with rectangular pushers with a 36mm case. Early 2508s had the serial numbers punched on the caseback, whereas the last generation, like the present example, had the 6 digit number finely engraved at the edge of the back. The large “Calatrava” style case, the superb untouched silver dial with black tachymeter and telemeter scales and the blue hands standing proudly against the silver dial are proof of the vivid modernism of this striking example. It is wonderful to see how a precisely 70-year-old chronograph wristwatch can be as timeless and contemporary today as it was when first launched. The present lot is in immaculate condition, the case maintaining all its angles and brushed surfaces. Furthermore, the case number and Rolex crown engraved on the caseback are perfectly crisp, the arresting dial showing no losses or signs of wear (something quite unheard of for a timepiece of this age with a non waterproof case), and even the original Rolex strap remains fitted, making us believe that the present lot spent most of its life in a safe - hardly worn and protected from the natural elements.
