Series 4 and 5
Why does Apple not sell the apple watch series 4 or 5? They still sell the series 3 but not 4 and 5, why? Is there problems with those particular models?

The manufacturing lines for the Series 6 is mostly the same kind of equipment needed for the Series 4 and 5.
It is much faster to switch an existing manufacturing line over to the Series 6, then it is to build new manufacturing, so they can continue with the older series.
The Series 3 had a different case, so they could not easily retool the series 3 line, thus is makes sense to keep the Series 3 as the low cost Apple Watch.
