Quick answer
The phrase covers a small ladies' watch sold as a copy of a Rolex Lady-Datejust. The name "Ladybird" comes from a Rolex ladies' line of the 1950s. The number "2033" comes from the seller listing, not from a Rolex catalogue. Case diameters run 25 mm to 26 mm. Movements are Asian automatic calibres, or Swiss ETA 2671 units in the top tiers.
Term breakdown
Ladybird
Rolex used "Ladybird" for small Oyster Perpetual watches made for women. Collectors apply the name to Lady-Datejust references with 26 mm cases. Current Rolex Lady-Datejust production uses 28 mm and 31 mm cases, so a replica sold as a Ladybird copies the older, smaller shape.
2033
Rolex service documents list calibres 2030 and 2035 in the ladies' automatic family. A calibre 2033 does not appear in those documents. Sellers use "2033" as a listing code for case diameter, dial layout, or a movement copy. Ask the seller what the number refers to. Most cannot say.
What ships in the box
Case: 25 mm or 26 mm stainless steel, sometimes plated with 18k gold or a gold-colour coating. Plating thickness runs 3 to 10 microns. Solid gold is absent at replica prices.
Movement: Asian copies of the ETA 2671 or the Rolex 2035. Beat rate is 21,600 vibrations per hour in most units. Power reserve is 38 to 42 hours. A real ETA 2671 measures 7¾ ligne, which fits a 26 mm case.
Dial: printed or applied markers, CZ stones on diamond-set versions. Cyclops magnification is often 2.0x against the 2.5x on a Rolex crystal. Case weight for steel runs 40 to 55 grams.
Price bands
- Under $80: steel case, plated finish, low-grade automatic or quartz, mineral glass.
- $120 to $250: 316L steel, sapphire glass, Asian 2671 copy, screw-down crown.
- $300 to $600: "super clone" claims, decorated movement plates, cleaner dial printing.
These bands come from listings seen in 2024 and 2025. Sellers shift them with gold content and stone type. Factory names change, and the same watch gets renamed.
Checks before payment
- Ask for movement photos with the caseback off. Reject stock images.
- Ask for the case diameter measured with calipers in the photo.
- Ask for plating thickness in microns.
- Inspect rehaut engraving. Copies show shallow or uneven letters.
- Compare the crown logo against a real signed crown.
Legal status in the United States
Counterfeit watches are illegal to import and sell in the US. 18 U.S.C. § 2320 covers trafficking in counterfeit goods, with prison terms and fines. CBP can seize shipments and issue civil penalties. Rolex holds the trademark, and customs officials target parcels with branded packaging. Payment disputes are hard to win because the transaction itself is unlawful.
Open questions
No public source confirms a Rolex calibre 2033. No public source confirms a factory that makes the "Ladybird 2033." Treat factory claims as unverified. Confirm case size, movement type, and plating in writing before any payment.
