NOS SEALED Rolex Sea-Dweller Ref. 16660 and Ref. 16600 bezel insert

The Rolex Sea Dweller Ref. 16660, also known by collectors as ‘Triple Six’, was released in 1978 as a replacement of the Ref. 1665, and so, it is considered a transitional model.

Rolex eventually discontinued the Ref. 16660 in 1988 leaving space for the newer Ref. 16600.

Offered for sale here is a bezel insert correct for either the Rolex Sea-Dweller Ref. 16660 or the Ref. 16600.

It is preserved in New Old Stock (N.O.S.) condition, remaining still in its original, unopened, factory-sealed plastic case.
