Rolex Sea-Dweller 4000ft 16600 Discontinued 2002 [Preowned]

Overview 

The Rolex Sea-Dweller 16600, produced from the late 1980s to around 2008, holds a special place in the brand’s diving watch history. With a 40mm stainless steel case, it maintains the classic Submariner proportions while offering a significant increase in water resistance—rated to 4,000 feet (1,220 meters)—thanks to its thicker case, crystal, and the inclusion of a helium escape valve. Its discreet design and tool-watch functionality make it a favorite among collectors who appreciate understated capability and professional-grade performance without the bulk of more modern iterations.

Unlike the current Sea-Dweller 126600, which measures 43mm and includes features such as a cyclops lens over the date and more prominent case proportions, the 16600 remains a more compact and stealthy option. Its lack of a cyclops lens was once a defining feature that set it apart from the Submariner Date, reinforcing its purpose-driven aesthetic. It also predates the use of Rolex’s modern Cerachrom bezels and larger “super” cases, offering a more traditional look and feel on the wrist.

In terms of wearability, the 16600 sits neatly between the classic Submariner and the oversized Deepsea Sea-Dweller. While it offers significantly more depth rating than the Submariner, it avoids the massive wrist presence of the 44mm Deepsea. This makes the 16600 an ideal choice for those who want professional dive watch credentials in a case that retains daily-wear comfort and versatility.

Now discontinued, the 16600 has gained cult status for its balance of old-school Rolex charm, robust performance, and practical sizing. It represents a key transitional period in Rolex’s tool watch evolution—bridging vintage and modern without leaning too far in either direction. For many, it remains the "just right" Sea-Dweller that honors the brand’s dive watch legacy while offering timeless wearability.

This particular reference is the 16600 and is a discontinued reference.
