Eternity 28mm Diamond Watch, 18K Rose Gold, Black Dial, Full Set, 2026","description":"\u003cp\u003e\u003cstrong\u003eHeritage\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe Tiffany \u0026amp; Co. Eternity watch is among the most jewel-forward expressions in the house's storied watchmaking tradition — a piece that exists at the precise intersection of haute joaillerie and fine horology. The cushion-shaped case in 18k rose gold carries the Eternity's defining character: a diamond-set bezel encircling a black lacquered dial where twelve individually hand-set diamonds — each a different cut — replace conventional hour markers with a collector's compendium of the jeweller's art. The diamond-set crown and diamond-set buckle complete a watch that was never intended to simply tell time. Reference 2N3120003 arrives new with box and papers, a current piece in active production. Scarcity here is not manufactured. It is earned.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDesign\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe 28mm cushion-shaped case in 18k rose gold presents a bezel set with round brilliant diamonds framing a black lacquered dial with twelve hand-set diamonds in twelve distinct cuts: round brilliant, baguette, cushion, Tiffany True®, marquise, Asscher, heart, pear, oval, emerald, triangular, and princess. 1.63 carats total weight. The diamond-set crown at 3 o’clock adds a final jewelled flourish. A black brushed calf leather strap with an 18k rose gold buckle set with 10 round brilliant diamonds completes the composition. Swiss quartz movement. 30m water resistance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCollector's Note\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe Tiffany Eternity in rose gold with full diamond setting and black lacquered dial occupies a singular position in the fine watch market — equally coveted by serious jewellery collectors and watch connoisseurs who understand that no two hour markers are alike.
