The Rolex Submariner Date Ref. 16618 with a "purple dial" is a highly coveted vintage timepiece from the early 1990s, particularly those produced around 1990–1991 (typically E or N serial numbers). This rare coloration is a "tropical" aging effect where the original blue sunburst dial has naturally evolved into a vibrant purple or violet hue due to specific pigment reactions.

• Case & Material: 40mm Oyster case crafted from solid 18k yellow gold.

• Dial: Features a rare purple/violet tropical patina.

• Luminescence: Original models from this era utilize tritium hour markers, which often age to a warm beige or cream color.

• Movement: Powered by the reliable Rolex Caliber 3135 automatic movement.

• Bezel: Unidirectional rotating gold bezel with a blue aluminum insert.

• Bracelet: Solid 18k yellow gold Oyster bracelet.

• The "purple dial" is not a factory-produced color but a unique aging phenomenon found only in a small batch of watches from the early 90s, making each piece distinct.
