Answer first
Replica Ladybird 6688 is a seller label, not a watch reference. No Swiss maker publishes a Ladybird model with the number 6688. The phrase appears on marketplace listings, in most cases from sellers in China. Ladybird is a style name used by several fashion brands. 6688 is a four digit SKU that a seller assigns. Two sellers can use 6688 for two different watches.
What the code does not tell you
A listing with this label gives no data on five parts of the watch.
- Movement. Quartz units and automatic units appear under the same label.
- Case size. Lady size cases run 26 mm to 34 mm. The digits do not encode the size.
- Case material. 316L steel, plated brass, and gold tone PVD all appear.
- Glass. Mineral glass on most units. Sapphire shows up at higher prices.
- Water resistance. ISO 22810 sets water resistance testing and marking for watches. Replica supply chains publish no test report. A 30 m claim on a page is a claim only.
Price bands
Listings for this label run from about $30 to $120. Units listed above $200 carry words such as 1:1 and Swiss super clone. No lab has published a comparison of those claims. Movement origin is the main cost driver. A Japanese quartz movement costs less than a Swiss ETA. Most listings show no movement photo.
Legal position in the United States
US law bars import of goods that copy a registered trademark. 19 U.S.C. 1526 lets US Customs and Border Protection seize such goods. 18 U.S.C. 2320 makes trademark counterfeiting a federal crime. A buyer can face seizure of the parcel and a letter from CBP. Resale adds separate exposure. A replica carries no manufacturer warranty and no service network.
Six checks on any listing
- Ask for the movement caliber and a photo of the caseback.
- Ask for case diameter in mm and lug width in mm.
- Ask for case material, not a color word.
- Ask for glass type: mineral or sapphire.
- Ask for the return window in days and who pays return shipping.
- Compare the same SKU on three sites. If the photos differ, the code means nothing.
What is unknown
The source of the 6688 code is not documented. No factory registry assigns it. Search results return different watches on different sites. A page that presents 6688 as an official model number is not reliable.
