The present stainless steel reference 3135 is, without exaggeration, one of the most beautiful, rarest and best preserved examples to come to the market in years. The multi-tone silvered sector dial is one of the rarest versions for bubblebacks and is a very typical design, used by many distinguished manufactures, between the late 1930’s and early 1940’s. As a scholar would expect, the correct hands to match this dial design are of blued steel. The case is in virtually perfect condition and shows no polishing whatsoever. In fact, the diamond polished bezel has retained its perfect mirror finish. The crystal, now with crazing, also appears to be the original one. To round up and complete this perfect example, a beautiful Rolex stainless steel grain de riz (rice grain) bracelet is mounted on the watch. Bubblebacks uniting so many highly attractive and rare elements, like the present one, are much rarer than many Rolex sports watches from the second half of the twentieth century. In our view, they are until now undervalued treasures and avid collectors should not wait too long.
