This Rolex Deepsea 116660 replica is the 44mm full-size Sea-Dweller Deepsea that established Rolex as a serious player in extreme-depth diving watches. The genuine 116660 carries a depth rating of 3,900 meters — nearly four kilometers beneath the surface — achieved through a case construction that includes a nitrogen-alloyed steel compression ring and a 5.5mm-thick sapphire crystal. At 44mm on the wrist with a case thickness approaching 18mm, this is one of the most physically imposing watches in the Rolex range — only the later 50mm Deepsea Challenge is bigger. The black dial keeps legibility straightforward with large luminous markers and a bold minutes hand.

Case & Movement Specs

• Case: 44mm stainless steel (the genuine is Oystersteel), approximately 17.7mm thick, helium escape valve at 9 o’clock
• Bezel: unidirectional rotating, black ceramic insert
• Dial: black with large luminous markers, date at 3 o’clock without Cyclops
• Crystal: domed sapphire (the genuine’s is 5.5mm thick)

• Power reserve: 48 hours (clone Cal. 3135)
• Water resistance: 100 m

The Glidelock clasp allows approximately 20mm of micro-adjustment without tools, which is essential for fitting the bracelet over a dive suit. The spring-loaded Fliplock extension adds even more length when needed.

Rolex Deepsea 116660 Caliber Breakdown

Inside this 116660 replica sits a clone Cal. 3135 automatic that drives hours, minutes, sweeping seconds, and a date display at 3 o’clock. The Deepsea case design uses what Rolex calls the Ringlock System — a compression ring sandwiched between the crystal and the caseback that allows both to withstand pressure independently. On the genuine, this engineering is what makes the 3,900m rating possible without making the watch entirely unwearable on land; the clone copies the Ringlock proportions and is rated to 100 m of water resistance, not to the 3,900m pressure rating. The black dial 116660 is the original Deepsea colorway. For a slimmer Sea-Dweller, look at the Sea-Dweller 126600 or browse the full Deepsea catalog for gradient and yellow gold options.

How It Compares

Next to the D-Blue 126660, the black 116660 is subtler and more traditional. It does not have the gradient drama but instead delivers a clean, high-contrast tool-watch face. The 44mm size means this is not a watch for slim wrists — it was built to be read at depth, in low light, through a face mask. For buyers who want the maximum Deepsea presence in the classic black dial configuration, this Rolex Deepsea 116660 replica is the definitive version of that concept.
