Lot Essay
The present watch was fully serviced by Rolex, Genève this year and is offered in superb condition, still retaining the protective service stickers to the sides and back. It offers a rare opportunity for a collector seeking a special Rolex dive watch of tremendous rarity.
The Sea-Dweller, ref. 16660, also known as the "Triple Six”, was introduced in 1978 and made until 1988. It replaced the reference 1665 with an increased depth rating of 1220 metres instead of the previous 610 metres, sapphire crystal, larger helium escape valve and caliber 3035 movement. Over the course of its brief ten year production run there were a total of five different dial evolutions. The first two were matte with luminous indexes directly on the surface. Those dials later evolved to gloss with luminous indexes in white metal surrounds as in the present watch. It was replaced in 1988 by the reference 16600.
