Datejust 31MM

The 31mm Datejust occupies the sweet spot between the ladies' 28mm and the midsize 36mm, a proportion that flatters nearly any wrist. It has become increasingly popular with buyers who find 28mm too small and 36mm more watch than they want to wear daily. Our 31mm inventory runs from clean steel references with smooth bezels to two-tone examples with fluted bezels and diamond dials. Mother of pearl and colored dial options come through regularly. Every watch is authenticated in-house before listing, and our team can send wrist shots and additional photos on request.

The Rolex Datejust 31 is the mid-size sweet spot of the Datejust family: larger than the Lady-Datejust 28, more delicate than the 36, and the size where Rolex offers some of its most beautiful dial work, including mother of pearl, factory diamonds, and rich two-tone combinations in yellow and Everose gold. Every Rolex Datejust 31mm at My Watch LLC is authenticated in-house and backed by our Chrono24 Certified dealer status.

Popular Datejust 31 References

Current favorites include the 278273 two-tone yellow Rolesor with fluted bezel, the 278271 Everose Rolesor, and the stainless 278240. Diamond-dial and mother of pearl configurations on Jubilee bracelets are consistently our most requested Datejust 31 builds, and five-digit 31mm references offer a compelling entry into the two-tone Rolex look.

Who the 31mm Fits

The Datejust 31mm suits wrists from roughly 5.5 to 6.5 inches, a natural fit for most women and increasingly popular with buyers who prefer understated vintage-style sizing. Also see the Datejust 36mm and Datejust 41mm.

How much does a Rolex Datejust 31 cost?

Pre-owned Datejust 31mm prices typically start around $6,000 for stainless models, with two-tone fluted references like the 278273 trading between $10,000 and $14,000. Factory diamond and mother of pearl dials command premiums, ranging from $13,000 upward depending on configuration.

Is the Datejust 31 a ladies' watch?

Rolex positions the 31mm within its classic range rather than as a ladies-only model. While it is the most popular women's Datejust size, the market has shifted, and mid-size Rolex is now a deliberate style choice across the board. Browse our full Ladies collection for more.
