About the Rolex Deepsea 136660
The Rolex Deepsea sits at the summit of the Oyster Professional lineup, evolved from the Sea-Dweller lineage into a dedicated extreme-depth instrument. The reference 136660 succeeded the 116660, carrying forward the 44 mm Oystersteel case with its characteristic Ringlock System engineered to resist crushing pressure at extraordinary depths. The helium escape valve, unidirectional rotatable bezel with Cerachrom insert, and Oyster bracelet with Glidelock extension system are hallmarks that define every example in this reference. The D-Blue dial variant, famously associated with explorer James Cameron's Deepsea Challenge dive to the Mariana Trench, has become one of the most recognizable and sought-after Rolex dial designs in the modern era.
What to Look For
Buyers comparing 136660 examples should distinguish between the classic black dial and the gradient D-Blue dial, as the D-Blue references such as 136660BLUO command a different collector profile and can carry a premium depending on condition and market timing. Box and papers, service history, and bracelet stretch are key factors when evaluating any pre-owned Rolex Deepsea for sale, and the 44 mm case size means fit on the wrist should be a primary practical consideration.
Frequently Asked Questions
What is the difference between the Rolex Deepsea 136660 black dial and D-Blue dial?
The black dial reference 136660 offers a clean, high-contrast look that prioritizes dive legibility, while the D-Blue dial transitions from deep blue at the top to black at the bottom, referencing the ocean's gradient during deep descent. Both share identical case dimensions, materials, and mechanical specifications, so the choice comes down to aesthetics and personal preference.
Is the Rolex Deepsea 136660 worth buying pre-owned?
The 136660 is a current-generation reference with strong Rolex brand support, which means parts and service availability remain excellent for pre-owned examples. Buying pre-owned from an authenticated dealer like Bizak and Co. allows you to acquire the watch at a price that reflects real market value rather than retail scarcity, and all pieces are verified for authenticity before shipping.
How large is the Rolex Deepsea 136660 on the wrist?
The Rolex Deepsea 136660 measures 44 mm in diameter with a notably thick case profile necessitated by its Ringlock System, making it one of the larger and more substantial watches in the Rolex catalog. Prospective buyers with smaller wrists are encouraged to try the watch in person or request detailed case measurements, as the combination of case width and lug-to-lug span is significant.
