The last watch on this list of the most remarkable Rolex watches from the 1970s is the aaa quality fake Rolex Sea-Dweller ref. 16660 “Triple Six.” The watch was first introduced in 1978 and stayed in production until 1989. After the initial Sea-Dweller ref. 1665 models, this is the first model that is basically the archetype for the modern Sea-Dweller as we know today.

It is also known as the best fake Rolex Sea-Dweller 4000 because it is the first Sea-Dweller guaranteed to be water-resistant up to 1,220 meters or 4,000 feet. The improved water resistance was achieved by a thicker and bigger 40mm stainless steel case, a thicker sapphire crystal — replacing the previous acrylic crystal — and a more advanced helium release valve.

Additionally, high quality copy Rolex updated the date disc to lose its silvery finish and replace it with an off-white-colored disc, and the watch was equipped with a unidirectional bezel. Inside the 40mm case Rolex used the Caliber 3035 to power the watch. It was a significant update from the previous Caliber 1575. The movement has an operating frequency of 28,800vph, a power reserve of 42 hours, and features a quickset date. Looking at all the specs, the Sea-Dweller “Triple Six” is still very much an up-to-date watch.

Different dials create different appeal
Looking at the different dial variants produced over the course of its 11-year production run, there are two distinctly different variants. The early versions of the Rolex Sea-Dweller ref. 16660 replica for men feature a matte black dial with painted indexes. Later versions feature a glossy black dial with white gold indexes. As you would expect, the later versions can be considered the true first modern Sea-Dwellers, while the earlier versions keep some of that vintage appeal of its predecessor, the Sea-Dweller ref. 1665 “Great White.”

As we talk about vintage clone watches with vintage appeal, it probably comes as no surprise that the earlier models of ref. 16660 with the matte black dials and painted indexes are harder to find and go for substantially higher prices. It’s also why you will find a huge gap in prices for the same reference number. Prices for a Sea-Dweller ref. 16660 start at roughly 8-9K and move up all the way to 35–40K for a version with the first dial that comes with a box and papers. Both are great options because the Sea-Dweller “Triple Six” is a simply great watch. But considering most people’s budget — including my own — the version with the updated dial seems like the perfect option to own a piece of Rolex history.
