Introduction
First released in 1967, the Rolex Sea-Dweller was launched as an upgraded version of Rolex’s ever-popular Submariner collection. With an increased water resistance of 610m versus the Submariner's 200m and a helium-escape valve to alleviate pressure within the case during its wearer's ascent back to the surface, the Sea-Dweller was a dive watch truly built for professionals. Amongst its many variants, the ref. 16600T that we have here debuted in 1988 and saw the longest production periods out of any Sea-Dweller – 20 years, with its discontinuation in 2008 leaving room for Rolex to introduce the Deepsea. With its black dial and aluminum bezel, lack of cyclops date magnifier, solid end links, and comfortable 40mm stainless steel case, the Sea-Dweller ref. 16600T blends some of watchmaking's creature comforts, in its robust construction, with some pieces of vintage detailing like its bezel and old-style Oysterlock clasp that have enabled it to remain a truly iconic piece of Rolex design and engineering.

THE CONSTRUCTION
Measuring 40mm in diameter and just under 15mm tall, the Sea-Dweller ref. 16600 pre-dates Rolex’s move to make the Sea-Dweller a far larger watch than what inspired it, the Submariner, and hence retains a familiar presence on the wrist.

THE CONDITION
Presented in like new condition, this example retains an almost completely unblemished surface with just some very light signs of wear across its construction. Coupled with its complete set, this is nearly as you would have gotten it from the AD in 2008.

TIMING MACHINE READOUT
This reading was taken (crown down) with a ONEOF Accuracy Boutique Edition timing machine at time of cataloging. It is provided as a courtesy only, and shall not be construed as a warranty or guarantee of any kind. Please refer to our terms and conditions of sale for more information.
Condition
Watch is in near-mint condition and appears only lightly used. Case has sharp edges and no dings or scratches visible on the surface. The caseback enameling is strong and fully visible. Bezel is free from scratches and the dial and hands do not show any wear. The bracelet has 14 links total, 4 of which are removable.
Our Perspective
An iconic piece of watchmaking, it wasn’t often that these timepieces were preserved in condition like the examples we have here, let alone with their complete full sets. Such was the infancy of the watch investment market at the time compared to today; watches were typically worn as they were intended. As a result, watches like our example here are scarce indeed.
