The Rolex Day-Date reference 18078 is a 20mm timepiece in Yellow Gold presented in used condition. Every watch is inspected and authenticated by our specialists before it is offered, so you can buy with confidence.
Pricing across the Day-Date runs from about $10,370 to $200,647. Plain-bezel yellow-gold pieces anchor the entry point, while fully diamond-set white-gold references reach the ceiling. Gem-set dials and RBR diamond bezels carry the highest premiums, and fluted or smooth bezels typically retain value more reliably. We help you read that spectrum honestly, matching specification to budget with a verified condition assessment. Read the full Day-Date buying guide ›
Durability and precision turned a 1905 Geneva start-up into the benchmark for mechanical watches. Hans Wilsdorf built Rolex around waterproofing, self-winding movements, and date displays, and the brand now leads the prestige sports market while trading like an asset class. Before you decide, we confirm the Oyster case, Perpetual movement, and Cyclops lens in house. With Submariner, GMT-Master II, and Daytona above retail, that verification earns its place.
