Median price per month or quarter. A point needs at least 3 records in its month or quarter; a gap in a line means too few records, and nothing is filled in. Forum prices are the price a seller listed on Reddit r/Watchexchange, RolexForums or WatchUSeek when the post was marked sold, not a confirmed sale price. Historical context only: these series do not feed the price shown above.

About the Sea-Dweller 4000 16600

The Rolex Sea-Dweller 4000 16600 is a reference in the Rolex Sea-Dweller collection. Rolex made it from 1989 to 2009. From our catalog: a 40 mm case in Stainless steel; bezel: Rotating stainless steel bezel with black insert, 60-minute scale; dial: Black; movement: Calibre 3135. 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

The range for the 16600 rests on 435 sold results (417 eBay sales and 18 auction results), and the sales we list run from November 2023 to October 2026. No month was busier than May 2026, when 43 changed hands. Hammer results come from Grailzee, Antiquorum and Phillips. Few references earn our top rating; this one does, thanks to a dense and consistent stream of results. Its latest sale is recent, inside the last fortnight. Recent prices sit close together (Stable, a typical spread of about 10% over 90 days). A fair price for the 16600 can sit anywhere from about 25% below to 25% above the midpoint. It trades often, so older sales fade quickly (a half-life of 30 days).

Its median over the last twelve months is 6.2% higher than the twelve months before, on 267 and 168 sales. Taking the longest view our archive allows (auction results since 2002), the latest year is up 202% on the opening year; the series bottomed in 2026 and topped out in 2021. Saleroom and marketplace disagree by about 11%: eBay sits below the auction median, based on 256 eBay sales against 11 auction results.

Sellers without the original box and papers should expect roughly 13% less; that discount comes from 14 watch-only results in the same family. Of the 741 sales listed, 183 came as a full set, 19 as the watch alone and 98 with part of the set; 15 were described as unworn. Unworn full sets sell about 5% above worn ones across our data, so an unworn example sits above the headline. Cheapest in the list: May 6, 2026, on eBay, set not stated, about 55% below the worth-about figure. Dearest: December 29, 2023, on eBay, unworn, full set, about 116% above the worth-about figure.
