The Rolex 278271 is the reference for the 31 mm Datejust in Rolesor, meaning a case and bracelet that mix Oystersteel with Rolex's Everose gold. If you searched this reference hoping to find a "replica 278271," the honest answer is that no replica reproduces the watch. The genuine piece runs a Syloxi-hairspring calibre 2236, a solid Everose gold bezel, and case finishing that counterfeit producers approximate rather than match. Buying or selling counterfeit watches also carries legal exposure in the United States. What follows is what the reference actually is, how its variants differ, and what to verify before you pay for one.
What the reference number covers
Rolex does not publish a public key to its reference codes, and the trade reads them as a family-and-material shorthand. The 278271 sits in the 31 mm Datejust line built around the calibre 2236, and the same reference covers several builds: fluted bezel or diamond-set bezel, Jubilee or Oyster bracelet, and a range of dials. The exact configuration is pinned down by the dial code on the warranty card and the model number on the paperwork, not by the base reference alone. Two watches sold under 278271 can look nothing alike.
The specifications that decide the experience
- Case: 31 mm Oyster, Oystersteel middle case with an Everose gold bezel and crown.
- Movement: calibre 2236, automatic, Syloxi silicon hairspring, roughly 55 hours of power reserve.
- Water resistance: 100 m, with a Twinlock screw-down crown.
- Crystal: sapphire with a Cyclops lens over the date at 3 o'clock.
- Bracelet: Jubilee with a concealed Crownclasp, or Oyster with an Oysterclasp.
Everose is not ordinary rose gold. Rolex adds platinum to the alloy to hold the colour, and that is one reason the gold parts age differently from the plating used on counterfeits.
Dials, bezels, and bracelets
Dial choice drives most of the visual character and most of the secondary market spread. Sunray finishes read sportier, while mother-of-pearl and diamond-set dials read dressier. The fluted bezel is the classic Rolesor signature, a diamond bezel pushes the watch further upmarket, and a smooth bezel keeps it quieter. Bracelet choice changes weight and balance more than photographs suggest, so try both if you can.
Why a replica 278271 is not a shortcut
Counterfeit watches are not a grey-market version of the real thing. They are trademark-infringing goods. In the US, Customs and Border Protection can seize shipments of counterfeit trademarked merchandise, and trademark owners can pursue civil claims against sellers, and in some circumstances buyers. Setting legality aside, the practical gap is large. No replica carries a genuine Rolex movement, so there is no factory service, no parts path, and no warranty. Resale value is effectively zero, and private sellers frequently pass counterfeits off as genuine to buyers who cannot inspect a movement.
- Pros of genuine: real movement, factory service, retained value, provable provenance.
- Cons of genuine: high entry cost, and limited availability on in-demand dials.
- Pros of a replica: lower upfront cost, and nothing else.
- Cons of a replica: illegal to import or sell, no service path, no resale, frequent misrepresentation.
What to verify before buying the real thing
Buy from an authorized dealer when you can. On the secondary market, confirm the warranty card matches the case and movement numbers, check that the Cyclops magnification and date alignment look correct, and look for the Everose hallmark on the case. Ask for service records and the original box and papers. Price moves with dial, bezel, bracelet, and completeness of the set, so compare several listings instead of trusting any single quote.
Who this watch suits
The 31 mm Datejust is the dressier, midsize option in the line. It fits wrists that find 36 mm or 41 mm too large, and it works as a daily watch for someone who wants gold in the mix without a full gold case. If you want a sports Rolex, this is the wrong reference. If you want a two-tone dress watch that stands up to regular wear, it is one of the better answers in the catalogue.
