Rolex Sea-Dweller Ref. 16660 - Triple '6'
Straight Facts
The Sea-Dweller ref. 1665 first debuted circa 1967 and was designed for use during saturation diving. Designed for people who needed something more robust than what a Submariner can offer. Of course, as we know sometimes the earliest generation does not end up being the icon.
The key differentiator between a SeaDweller and Submariner, is that the SD always has a helium escape valve on the side, and usually a higher domed crystal with no cyclops magnifier. This - overall - created a much cleaner look.
This present “Triple 6” model comes from a transitional time for Rolex. At the time, Rolex was starting to straddle the line between the original ‘serious tool watch’ designs that Rolex intended for, and a high-cost luxury goods item. The matte dials gave way to these high gloss dials which feature plots of lume surrounded by white gold, very luxurious! Since today you can purchase a Sea-Dweller in 18K Yellow Gold & Steel! - we all know which side won out between luxury and sport at the brand with the coronet! The overall condition of the present watch is strong with no signs of abuse or over polishing throughout its life. That is no small feat as these were truly purchased only by serious professionals who used them in underwater feats of engineering!
We couldn’t be prouder to offer this example - and hope that you enjoy wearing it as much as we enjoyed sourcing it!
