Sample vs. swatch

Sample and swatch，中文都叫樣本或樣品，但sample比較是通稱，swatch則常用來指被裁成小塊布(常集結成冊)的樣品布，或者印刷業，用來比對顏料和紙材的樣品紙或色卡:

"Swatch" is a sample of cloth used as an example to demonstrate the color, pattern, and texture of a fabric.

On my mind: 

Does anyone know that the famous watch brand "Swatch" has anything to do with the word we just learnt?
