The EEC filings by Apple, first spotted by Consomac, consists of 14 model numbers, all following the same format of the letter A followed by four numbers. While most correspond to the Apple Watch Series 1, Series 2, and Series 3, six of the model numbers do not relate to any current or previous Apple Watch model at all.
The model numbers in question are: A1975, A1976, A1977, A1978, A2007, and A2008.
It is thought the six model numbers means there will be six models in the Series 4 range, down from the eight models offered under Series 3. It is unknown why, but it could mean the removal of one of the case material options from the roster, which currently consists of aluminum, steel, and ceramic.
