It probably refers to the gold content. Au being the scientific abbreviation for gold.

AU is the chemical symbol for gold.The 10 means the micron depth of the layered gold.If a watch has AU10 stamped on it it means it has been gold plated to a depth of 10 microns (around 0.010mm or 1/100th of a millimetre thick).
