Rolex Sea-Dweller 1665-Rubber Strap Option

[swish77]

I had been looking for a while for a perfect-fit rubber strap for my 1665, and I finally found one. The Rubber B strap that is advertised as fitting the 16660s also works very well on the 1665s. Just because a strap is 20mm doesn't mean it will work well on an old Sea-Dweller because of the thickness of the case. The Rubber B thickness works very well with the curve of the lugs. I hear the Everest bands are also great, but I don't know how well they fit vintage models. Both brands are relatively pricey, but if you want that seamless, curved-end fit, you don't have much of a choice.
