The Rolex Day-Date reference 218348 is a 41mm timepiece in 18K Yellow Gold presented in used condition. This piece is customized — aftermarket-modified (setting or dial added outside the manufacturer); not original factory condition. Every watch is inspected and authenticated by our specialists before it is offered, so you can buy with confidence.
Collectors approach the Day-Date by size first. The classic 36mm spans references 1803, 18238, 128238, 128239 and 128345, while the larger 40 and 41mm sits with 218238 and 228348. Every case is solid 18k yellow, white or Everose gold, since no steel version exists. Our desk confirms case, dial and bracelet authenticity so you can choose on character rather than guesswork.

Today Rolex dominates the prestige sports-watch market and functions as much as an asset class as a timepiece. The brand, founded in 1905 by Hans Wilsdorf, pioneered waterproofing, self-winding movements, and date displays from its Geneva manufacture. Our authentication covers the Oyster case, Perpetual movement, and Cyclops lens. Since steel references trade above retail and supply stays tight, expert guidance helps you buy the right piece.
