1930s Rolex Oyster Bubble Back Ref.3131 in 18k yellow gold rare "Yellow on Yellow"

This is a late-1930s Rolex Oyster Bubbleback Ref. 3131, an 18k yellow gold model with a yellow-colored dial. As expected of a solid 18k gold Bubbleback, this piece has a notable sense of weight and presence. It features a stunning "yellow-on-yellow" combination, with the yellow gold case harmonizing beautifully with the yellow-colored dial, making it a rare and exquisite piece. It is a double-signed model that was sold at the Swiss jeweler "ERBE-BASEL." The crownless design, characteristic of this era, also adds to its appeal.
