£11,000.00

  • Year: 1983.

  • Movement: Automatic 3035 Rolex movement.

  • Case: 40mm steel case with deep holes and unpolished.

  • Dial and bezel: Original Mark 1 matte dial which has developed a incredible dark toned patina. Dial is in very honest condition with matching tritium lume to the hands. The lume on the dial and hands reacts to UV light but holds no charge so correct for the era. Original flat 4 bezel insert with dark toned lume pip.

  • Crystal: Sapphire crystal.

  • Strap: 93510 Oyster bracelet with 532 end links with F year stamping.

  • This watch is sold as watch only, which is typical for vintage timepieces. We place greater value on condition, originality, and overall integrity than on whether a box or papers happen to be present. Many vintage watches have lost their packaging over time, and we don’t believe in inflating prices with non-original extras.

    If a watch does include genuine box and papers, this will always be clearly noted in the description. All purchases come with bespoke Watts On Watches packaging and full purchase documentation.

  • Every watch we sell is fully inspected and professionally serviced to meet our exacting standards. We stand by the quality of our stock, which is why every purchase comes with a 12-month warranty as standard.

The Rolex Sea-Dweller Ref. 16660 represents one of the most important transitional references in Rolex’s dive watch history. Often referred to by collectors as the “Triple Six” or “Great White”, it bridges the gap between the vintage Sea-Dwellers of the 1970s and the more modern references that followed.

This 1983 example is exactly the type of watch collectors look for today. Honest, original and beautifully aged.

The Mark 1 matte dial has developed a deep, dark tone over the decades that gives the watch tremendous character. The tritium lume plots have aged naturally and remain well matched with the original tritium hands. Under UV light the lume reacts briefly but holds no charge, exactly what you want to see from original tritium of this era.

The dial is not overly cleaned, restored or artificially preserved. It shows its age honestly, which is precisely what makes it so appealing.

A Word on Condition

This watch is best described as honest.

The case remains unpolished with strong edges and visible lug holes, exactly the kind of case collectors hope to find on vintage Sea-Dwellers. It shows natural wear consistent with its age, but the geometry of the case remains intact.

The dial has developed a darker toned patina that gives the watch depth and personality. The tritium lume plots remain intact and evenly aged, matching the handset beautifully. The bezel insert is correct with the desirable flat 4 font and a dark toned lume pip that complements the dial perfectly.

Nothing about this watch feels over restored or artificially preserved. It is simply an authentic, well aged Sea-Dweller that has lived an honest life.

Why Buy This Watch

The 16660 is one of the most important Sea-Dweller references ever produced. It introduced the sapphire crystal and the calibre 3035 while still retaining the charm of matte dial Rolex sports watches.

Collectors increasingly value examples that show honest ageing and retain their original components rather than pieces that have been heavily refinished or rebuilt.

This watch is sold as watch only, which is typical for vintage timepieces. We prioritise condition, originality and overall integrity over the presence of box and papers. All purchases are supplied with bespoke Watts On Watches packaging, full documentation and a 12 month warranty as standard.

A true vintage Sea-Dweller with the kind of honest character collectors search for.
