The reference 179171 is a Rolex Lady-Datejust 26 mm in Rolesor, which means a stainless steel case matched with an 18 k Everose gold fluted bezel and a two-tone Jubilee bracelet. A "fake 179171" is any watch sold under that reference number that Rolex did not produce. Counterfeits of this model run from obvious costume pieces to close copies built with cloned cases, aftermarket dials, and generic automatic movements. The fastest way to sort them is to check the rehaut engraving and the movement first, then work outward to the dial, bezel, and bracelet.
What the 179171 Should Be
Knowing the genuine specification makes the fakes easier to catch, because most copies miss at least one detail.
- 26 mm Lady-Datejust case in stainless steel with an Everose gold fluted bezel
- Calibre 2235 automatic movement with date, hacking seconds, and quickset date
- Sapphire crystal with a Cyclops lens over the date at 3 o'clock
- Jubilee bracelet with gold center links and a concealed Crownclasp
- Plain caseback, 100 m water resistance, serial engraved on the rehaut
Fast Checks That Expose Most Fakes
Run these in order under good light and a loupe before you discuss price.
- Look at the inner ring around the dial, called the rehaut. Genuine examples carry repeating ROLEX engraving with the crown aligned at 12 o'clock and the serial at 6 o'clock.
- Compare the rehaut serial with the number on the warranty card and, if you can see it, the movement.
- Check the date window. It should sit under the Cyclops at 3 o'clock, centered, with roughly 2.5x magnification and a clean edge.
- Hold the watch in your hand. A real Rolesor reference has heft from the solid gold bezel and center links, while plated copies feel light and hollow.
- Inspect the bezel flutes. Gold flutes are cut with sharp, even angles and reflect a warm rose tone, not a yellow or gray cast.
- Turn the crown and confirm the date changes and the seconds stop when the crown is pulled out.
Dial, Crystal, and Date Window
Dial printing is where most replicas fall apart. Under magnification, the text on a genuine dial has crisp edges and consistent spacing, and the crown logo is applied with defined points. Diamond markers on the 179171 are set by hand in a gold grain setting, so the metal around each stone is smooth and even. On copies, the printing looks soft or thick, the lume plots sit unevenly, and the Cyclops lens tends to look cloudy or magnify too little.
Case, Bezel, and Gold Color
Check the lugs and the case sides for polishing quality. A genuine case has flat, mirror-polished surfaces with sharp transitions at the lug edges, and the gold bezel is solid Everose, not plating. Plated bezels wear through at the flutes and the edges within months, showing gray steel underneath. Look also at the crown on the case side: it should sit flush, carry the coronet in relief, and turn with resistance rather than spinning freely.
Bracelet and Clasp
The Jubilee bracelet on this reference uses solid center links in gold with steel outer links. Run a fingernail along the link gaps and check for stretch and rattle. Fakes often use folded or hollow links, stamped clasps, and a visible gap where the clasp closes. The concealed Crownclasp on a genuine bracelet opens with a firm release and sits flush with the link profile when shut.
Movement Check, the Deciding Test
No amount of external inspection replaces opening the caseback. This is the single step that ends the debate.
- Ask the seller for clear photos of the movement with the caseback removed, or bring the watch to a watchmaker.
- Confirm the calibre marking reads 2235 and that the rotor carries Rolex engraving and finishing.
- Count the jewels and inspect the bridges for Geneva stripes and clean beveling.
- Verify that the serial on the movement matches the rehaut engraving.
- Decline the sale if the seller refuses an inspection during the return window.
Paperwork and Serial Matching
Cards, boxes, and booklets are the easiest items to copy, so treat them as supporting evidence rather than proof. What matters is that the rehaut serial, the movement serial, and the warranty card all agree, and that the card format matches the production era of the watch. A service record from an authorized watchmaker adds real weight to a listing. Blank or mismatched paperwork is a reason to walk away.
Legal Risk and Buying Rules
Counterfeit watches are illegal to import and to sell in the United States. Customs can seize shipments, and trafficking in counterfeit goods carries federal penalties. Beyond the legal exposure, a fake 179171 has no factory service support, no parts availability, and no resale value. Buy from an authorized dealer or a pre-owned specialist with a documented history, insist on serial matching, treat prices far below market for a solid gold bezel model as a warning, and get any private sale inspected before the return period ends.
