The Rolex “Bubbleback” is a landmark model in the history of the brand, representing a significant early achievement for Rolex and a precursor to the modern phenomenon of watch collecting. The reference 3131 Bubbleback in 14 kt pink gold, featured here, exemplifies the early elegance of Rolex design, with its smooth bezel, silvered dial, and a mix of Roman and baton indexes in a gilded tone. However, what truly distinguishes this timepiece is the historically significant engraving on its case back: “White Mouse Racing - Prince Bira - Maserati 4 CL Chimay Circuit - May 25, 1947.” Prince Birabongse Bhanudej Bhanubandh, known as Prince Bira, was a member of the Thai royal family and a pioneering race car driver who became a prominent figure in European motorsports during the 1930s, ’40s and ’50s. In 1947, he claimed victory at the Grand Prix des Frontières, held on the Chimay Circuit in Belgium, driving a Maserati 4CL entered by his own team, White Mouse Racing. The inscription on this watch suggests that it was presented to Prince Bira to commemorate his victory at this event, where he not only won the race but also set the fastest lap time. This historical context, combined with the well-preserved condition of the watch and its association with one of motorsport’s early international stars, makes it an extraordinary collector’s piece. Furthermore, its inclusion in the book “Time to Race Part II - Watches and Speed: Other New Stories of Men and Machines” by John Goldberger and Cesare Maria Mannucci adds to its provenance and appeal among collectors and enthusiasts.
