Collectors often start with the references. The ref. 1665, produced 1967 to 1988, established the COMEX link, and its double-red dial variants rank among the most sought-after vintage Rolex. The 16600 refined the 40mm formula through 2008. The 126600 and Rolesor 126603, from 2017, mark a 43mm 50th-anniversary relaunch. Dial originality matters enormously on early pieces, so we authenticate each in-house before it reaches you.

Two size epochs define buying decisions: the 40mm Sea-Dweller 4000 era, anchored by ref. 16600 (produced 1988–2008), remains the benchmark collector piece for its balanced proportions and strong secondary-market depth; the current 43mm generation—ref. 126600 in steel, ref. 126603 in Rolesor steel-and-yellow-gold—suits buyers seeking modern bracelet comfort and a contemporary movement. Water resistance is rated 1,220m (4,000ft). Value drivers include an unpolished case and bracelet, a functioning Glidelock clasp, and complete box-and-papers. The 126603's two-tone configuration commands a meaningful premium; dial originality and bracelet stretch each affect pricing materially on pre-owned examples.
The ref. 1665 (1967–1988) established the COMEX connection; double-red dial variants are among the most collectible vintage pieces. The 16600 (1988–2008) refined the formula at 40mm. The 126600 and Rolesor 126603 (2017–present) mark a 43mm 50th-anniversary relaunch.

Pre-owned steel 16600 and 126600 examples anchor the lower end; the Rolesor 126603 commands a significant premium reflecting its gold content and newer production. Current live range: $9,150 – $21,750. Prices shown are the full card price; bank-wire payment saves about 3.4%.
Model names, references and specifications are referenced from the official Rolex Newsroom (www.rolex.com). Trademarks and product imagery rights remain with the manufacturer; product photography shown is of our own inventory.
Most people land on a page like this for one of two reasons: they want to buy a Rolex Sea-Dweller, or they already own one and want to know the number. The prices above answer the first question — they are what the piece sells for once a specialist has cleared it.
For the second, send the reference and a few photographs. A specialist reads the case, dial, bracelet and papers and comes back inside one business day with a firm figure, taken as cash or as credit against something else. We cover fully insured shipping in both directions, so it costs nothing to find out and nothing to walk away.
