Rolex Oyster Perpetual “Bubbleback” Ref. 3131 – 14K Yellow Gold

This rare Rolex “Bubbleback” (Ref. 3131) is crafted in solid 14-karat yellow gold and dates from the 1940s, representing one of Rolex’s early automatic Oyster Perpetual models. The 32 mm gold case features the distinctive domed “bubble” caseback, and the cream dial displays elegant Roman numerals with gold hands, complemented by a blued steel seconds hand.

Powered by a Rolex automatic movement, often caliber 620, with 17 jewels and chronometer-grade precision, the watch is housed in a screw-down Oyster case. It comes with a period-correct leather strap, a vintage Rolex display box, and our official certificate of authenticity.

The Bubbleback collection was pivotal in Rolex’s evolution from manual-wind to fully automatic watches. Ref. 3131 combines timeless mid-century design, durable construction, and historical significance, making this 14K gold model a highly sought-after collector’s piece.
