Today's offering showcases this wonderful all-original ref. 3131 Bubbleback made circa 1946. Produced from 1939 to 1946, these exclusive watches are very fine and desirable.

Housed in one of Rolex's first water-tight Oyster cases, this wristwatch originally offered its owner complete protection against water and dust. Inside the ruggedly elegant case Rolex place an early self-winding Perpetual movement, keeping the watch powered by movements of the wrist.

Equipped with nineteen jewels, a self-compensating Breguet mainspring, and the company's patented Super-Balance system for greater accuracy, this fine watch the timekeeping standards of discriminating owners.

What separates this watch from other Bubblebacks its it beautiful all original condition. It parts are fully original down to all hands and its Rolex + Oyster winding crown. The dial was restored in vintage times.

The case has nice thick lugs which have not been over polished.

Our watchmaker has just freshly cleaned and oiled the movement which winds smoothly and is keeping accurate time.

For the finishing touch we have equipped it with a new Teju lizard strap making it ready for immediate enjoyment.

Included with the purchase is a one-year C.O.T. international warranty on the movement and its function, a custom printed Connoisseur of Time Certificate of Authenticity, and a new timing certificate.

Please note: A published example of this model can be found in Osvaldo Patrizzi's work Rolex, Collecting Wristwatches, 2001 Edition, Guido Mondani editor, Vol. 1, p. 214.
