Our take on the Rolex Sea-Dweller 40mm Steel Date Black Dial Automatic 16600

The Rolex Sea-Dweller 16600 is a 40mm stainless steel dive watch with a black dial, automatic movement and a steel bracelet. It is the last Sea-Dweller generation without a helium escape valve on the case side, which makes it slimmer and cleaner on the wrist than the later Deepsea line. It suits divers and collectors who want a serious tool watch that still wears like a classic Oyster. Against the Submariner it adds a date and a depth rating built for saturation diving; against the Deepsea it is smaller and easier to wear every day.

Best forCollectors of pre-Deepsea Rolex dive watchesDivers who want a date and a robust steel caseWearers who prefer a 40mm case over the larger DeepseaBuyers wanting a classic black-dial Oyster on steel
Pros
  • 40mm steel case wears comfortably on most wrists
  • Automatic movement with date and quick-set
  • Black dial with luminous markers is easy to read
  • Steel Oyster bracelet with a secure clasp
  • Last Sea-Dweller without a side helium valve, so a cleaner profile
Cons
  • No helium escape valve, unlike later Sea-Dweller models
  • Thicker case than a Submariner
  • Older examples may need servicing
  • No written warranty from the seller
  • Water resistance is stated at 50 m, far below the model's dive heritage

What is in the box?
The watch on its steel bracelet. Box and papers depend on the individual example, so check what is included.
