For sale is my Rolex Sea‑Dweller 16600, a late D-serial example representing one of the most desirable configurations of the classic five-digit Sea-Dweller. This watch was freshly serviced by Rolex (Dallas RSC) in November 2024 and is running perfectly. I explicitly requested no refinishing, and the case and bracelet remain unpolished, retaining strong factory lines and honest wear. This reference sits at the sweet spot of Sea-Dweller history — classic 40mm proportions, sapphire crystal, no cyclops, and the final era before Rolex fully transitioned away from traditional tool-watch design cues. ⸻ Details • Reference: 16600 • Serial: D-Serial (no lug holes) • Case size: 40mm • Movement: Rolex Cal. 3135 • Bracelet: Original Rolex Oyster bracelet • Crystal: Sapphire • Water resistance: 4,000 ft / 1,220 m ⸻ Condition • Excellent overall condition • Unpolished case and bracelet (no refinishing performed) • Strong case lines and crisp bezel • Runs exceptionally well post-service ⸻ Recent Rolex Service (11/2024 – Dallas RSC) • Complete movement overhaul • New Rolex crown & gaskets • Full pressure testing • No polishing per request • Rolex service warranty valid through November 2026 ⸻ What’s Included • Full Kit Rolex Sea-Dweller 16600 • Original Rolex bracelet • Original Rolex box and papers • Rolex service documentation ⸻ Price & Terms • $9,600 net to me • Wire or Zelle preferred • FedEx Overnight shipping, fully insured (CONUS) • Face-to-face transaction possible in Fairfield County, CT • Not interested in trades at this time This is a straightforward, properly serviced Sea-Dweller that’s ready to be worn daily or held long-term.
