Rolex’s references 8171 and 6062 are two of the most legendary mid-20th century timepieces, and the brands only models produced featuring triple calendar and moon phase. Today, collectors more closely associate Rolex timepieces with vintage and modern “tool” and sports wristwatches, however these mythical references are highly sought after, and rare to find. The reference 6062 featured the signature Oyster-case with a large 36mm diameter, while the reference 8171 boasted a robust 38mm case. Both models were produced during a short period between 1949 and 1952 and were available in yellow gold, pink gold or stainless steel. It is interesting to note that almost half a century would pass before Rolex re-introduced another Rolex model with moon phase, the Cellini Moonphase, which was released in 2017.
