About the Datejust 31 178343

The Rolex Datejust 31 178343 is a reference in the Rolex Datejust collection. From our catalog: a 31 mm case in Stainless steel and yellow gold; bezel: Set with 24 diamonds, 18k yellow gold; movement: Calibre 2235. 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

Our record for the 178343 covers about 26 months of sales, April 2024 to June 2026, and 12 of those results stand behind the current figure (11 eBay sales and 1 auction result). February 2026 saw the most activity, 3 sales in a single month. Hammer results come from Grailzee. Middle-tier confidence applies: enough evidence to frame a fair price, not enough to pin it tightly. No sale has arrived in the last 123 days, which slows how fast the figure can react. Recent trading is too sparse to say whether prices are calm or jumpy. Its band runs about 35% under the midpoint and 34% over it, a guide to how far a fair offer can stray. Because it changes hands rarely, a sale still counts for half after 180 days.

Year on year, the median sale is down 13.9% (6 sales against 6).

Missing the box and papers costs about 13% on this reference, going by 131 bare-watch sales across its line. Paperwork varied: 6 complete, 0 bare, 1 incomplete. The lowest listed sale, on April 11, 2024 (on eBay, good condition, set not stated), came in about 21% below the worth-about figure; the highest, on June 5, 2026 (at Grailzee, good condition, full set), about 25% above the worth-about figure.

Close to it on price in the same family: Datejust 36 126234 price, Datejust 31 278274 price and Datejust 41 126303 price.
