About the Datejust 31 78240
The Rolex Datejust 31 78240 is a reference in the Rolex Datejust collection. From our catalog: a 31 mm case in Steel. The specifications below list every fact we have sourced for this reference; anything we could not source is marked as not known.
What the sales say
Counting only completed sales, 37 sit inside the window that sets the figure (36 eBay sales and 1 auction result), and the dated list covers October 2023 to August 2026. June 2026 saw the most activity, 4 sales in a single month. Auction results here come from Grailzee. Middle-tier confidence applies: enough evidence to frame a fair price, not enough to pin it tightly. The newest sale is 74 days old, so the figure leans on older evidence. There were too few sales in the last 90 days for a volatility label. A fair price for the 78240 can sit anywhere from about 35% below to 35% above the midpoint. Sales are thin, so older results keep their weight longer (a half-life of 180 days).
Year on year, the median sale is up 4.2% (13 sales against 24). The record only reaches back to October 2023, short of the five years a long-run figure needs.
Without box and papers, the same 78240 is worth about 13% less on the ratio we measured for its collection (from 131 watch-only sales). Of the 55 sales listed, 9 came as a full set, 0 as the watch alone and 8 with part of the set. The floor of the list (April 27, 2024, on eBay, set not stated) is about 65% below the worth-about figure, and its ceiling (May 30, 2025, on eBay, set not stated) is about 38% above the worth-about figure.
