Quick answer
The Ladybird mother of pearl model is a Longines ladies dress watch. The dial is a thin sheet of nacre, not paint and not plastic film. Case sizes, reference numbers, and bracelet options change by year and by market. Check the Longines catalog page for the exact reference before you compare prices. Most versions run a quartz movement, a sapphire crystal, and a leather strap or steel bracelet.

What mother of pearl is
Mother of pearl is nacre. A mollusk builds it in layers of aragonite platelets bound with conchiolin protein. The layers sit at small angles to each other. Light returns from different depths, which gives the dial its shifting sheen.

Mohs hardness for nacre runs about 3.5 to 4. A fingernail is 2.5. Steel is near 5.5. Sapphire is 9. Nacre scratches, and acid etches it. Perfume, hairspray, and citrus juice all attack the surface.

Color comes from the shell source. White and cream come from common pearl oysters. Black and gray come from the black lip oyster, Pinctada margaritifera. Pink and blue tints appear in freshwater nacre.

Ladybird dial and case details
- Dial material: nacre sheet, cut thin. Most samples measure under 0.5 mm.
- Markers: metal indexes on some references, diamond indexes on others. Longines lists a color and clarity grade for the diamonds on the spec sheet of each reference.
- Movement: quartz on the references sold under the Ladybird name. Longines publishes the calibre number on the product page.
- Water resistance: 30 m on most dress references. ISO 22810 treats 30 m as splash protection, not swimming.
- Crystal: sapphire, domed on several references.
Why no two dials match
Nacre is a natural material. The grain, the pattern direction, and the exact shade differ from sheet to sheet. Two watches of the same reference will not carry identical dials. A buyer who wants a matched pair or one specific shade should ask for photos of the actual watch, not the stock image.
Care
- Wipe the dial and case with a soft dry cloth.
- Keep perfume, lotion, and hand sanitizer off the dial.
- Skip ultrasonic cleaning. The vibration and the bath can lift the dial sheet.
- Store out of direct sun. Nacre dries and yellows after long UV exposure.
- Service the quartz movement every 3 to 5 years, or when the battery indicator jumps in one second steps.
Buying notes
A printed or plastic dial looks the same from one angle and flat from all others. Real nacre shifts with the viewing angle and shows depth under a loupe. Replica listings often call a printed dial mother of pearl. Check the dial edge under a loupe. Nacre shows a layered edge. Print shows a hard line.
Longines does not publish a public lookup that ties a serial to the dial material. Match the reference number on the caseback to the catalog page before you buy.
