Rolex 278273 Counterfeit: The Short Answer
Match the reference to the metal, the movement, and the weight before you look at the dial. The Rolex 278273 is a Datejust 31 in stainless steel and 18k yellow gold, so any listing that shows a steel case with gold color painted on, a movement with no caliber name, or a bracelet that comes in far under the 90 to 110 gram band is a copy built to a spec sheet. Ask the seller for the movement caliber, caliper measurements of the case, a timegrapher photo, and the total bracelet weight. If those four answers do not line up, stop.
Read the Reference Group First
The 278 prefix places the watch in the Datejust 31 family. The 273 block marks a two-tone Rolesor build, meaning a steel case paired with 18k yellow gold on the fluted bezel, the winding crown, and the center links of the bracelet. The final digit separates bracelet styles, so a change in bracelet does not change the metal content. A seller who mixes these up is working from photos, not from a watch.

Weight, Size, and Proportions
Two-tone watches live or die on density. A complete Datejust 31 on a full bracelet sits in the 90 to 110 gram range, and the number moves with link count, so ask for the weight with the bracelet sized to the wrist being sold. Gold plated copies land 15 to 30 grams lighter because the core is steel or brass under a thin layer. Case diameter is 31 mm, case thickness runs near 10.5 mm, and the lug width sits around 16 mm on the two-tone version. Pull a tape measure. Copies drift on thickness because the movement inside is deeper than the 2236.
Gold Content and Hallmarks
Genuine gold parts carry the 750 stamp for 18k, and Swiss hallmarking applies to the gold components. Plated bracelets get stamped too, so the stamp alone proves nothing. Check the edges of the clasp, the crown, and the bezel flanks where plating wears through to a different color. Under a loupe, plated gold shows a soft transition at the edge, while solid gold keeps the same tone through the full thickness. A jeweler with an XRF tester can settle the question in a minute.

Movement Checks
The genuine 278273 runs Caliber 2236, a Syloxi hairspring design with a 55 hour power reserve and a 28,800 vph beat rate. Copies use a range of automatic movements, some decorated to look Swiss and some honest about their origin. Ask for a timegrapher reading that shows rate, amplitude, and beat error. A watch running outside plus or minus 10 seconds per day with amplitude under 250 degrees is not a Superlative Chronometer, whatever the dial says. Winding feel matters too. The 2236 crown turns with light, even resistance and screws down with a firm stop.

Where Counterfeit Listings Fall Apart
- Stock images lifted from a dealer site instead of photos of the actual unit
- Swiss made claims with no Swiss shipping origin and no service documentation
- Gold plating described as solid gold or as gold wrap with no thickness given
- One clasp code repeated across a whole batch of listings
- No return window, no tracking number, and no answer when you ask for a movement photo
- Cases that have been over-polished to hide soft lug shapes
Questions to Ask a Seller
- Which movement is inside, and who built it?
- What does the watch weigh on a scale, with the bracelet as shipped?
- Can you send a timegrapher photo with the watch running?
- Are the gold parts solid, plated, or wrapped, and how thick is the layer?
- What is the return window, and who pays return shipping?
- Are the photos of this exact unit, taken today?
FAQ
Did Rolex ever make a steel-only 278273? No. The reference covers a two-tone Rolesor watch. A steel-only Datejust 31 carries a different reference, so a listing that describes a steel case under this number has the wrong label.
Can I spot a fake from one photo? Not with confidence. Photos hide weight, movement, and plating thickness, which are the three things that separate a good copy from a bad one. Ask for video, a timegrapher, and a scale reading.
Will Rolex service a 278273 without papers? Rolex service centers inspect and authenticate before work starts, and they return watches that do not match factory specification. For a genuine watch, service history helps the process.
Does a replica hold resale value? No. The secondary market for copies is thin and prices fall fast once a newer batch ships. Treat the money as spent.
What matters most if I buy a copy? Movement quality first, then case and bracelet weight, then dial details. A strong movement on a well finished case beats a perfect dial on a noisy one.
