Rolex Seadweller 16600 with tritium dial from 1995. The dial and hands are in perfect condition and has heavy patina markers from sitting in a safe for over 22 years after being used vigorously as a dive and work watch. The case is in excellent vintage condition and has never been polished however shows wear in various places as it was used as a tool watch in the field. The movement is running strong and keeping excellent time.
the 16600 was launched by rolex in 1989 and very similar to its predecessor the 16660. It has a sapphire crystal and 1,220 meter water resistance. The 16600 was the longest production Seadweller (20 years) however its important to note that the tritium version was only produced from approximately 1989-1998. The luminous material transitioned from tritium to Luminova to SuperLuminova. You can easily identify the dial variant below the 6 marker at the bottom of the dial. T Swiss T<25 = Tritium, Swiss = Luminova, and Swiss Made = SuperLuminova.
the movement is the caliber 3135, an improved version of the caliber 3035 which has a longer power reserve and a full balance bridge. The reference 16600 was discontinued in 2009 and in recent months the tritium version especially in original unpolished condition have become very collectible and increasingly difficult to find. We suspect it will continue to grow in value and rarely as they further become unavailable.
