Late 1940s production Rolex Oyster “Bubble Back” Ref.3131 with a silver dial. This is a 14K yellow gold model featuring the popular bar index design.
The bar index style, favored since the 1st model, showcases a refined design characteristic of later examples: mirror-printed bar markers at the 3, 6, 9, and 12 o’clock positions, combined with black-printed bar indexes for the remaining hours.
The solid gold Bubble Back case, with its distinctive heft, is crafted in 14K yellow gold and—like early Bubble Back models—is constructed in a highly elaborate manner, consisting of a bezel, middle case, case back, and movement holder. The simple, timeless dial design ensures lasting appeal and makes this a piece that can be enjoyed for many years.
It comes fitted with a current JB Champion bracelet (suitable for wrist sizes up to 21 cm) and is accompanied by a later 18K yellow gold 14mm buckle.
