Rolex Oyster Perpetual "Bubbleback" Reference 3131
This Rolex Oyster Perpetual reference 3131 is an awesome example of an early "Bubbleback" dating to circa 1946. These early Oyster cases would help play a role in ‘How Rolex Became Rolex’.
It features an automatic calibre. The case is pink gold and measures 32.5mm in diameter (39.5mm lug-to-lug). I believe it is also unpolished.
The watch does not come with box and papers.
