Apple has been allowing their partners to aggressively price the "old" Apple Watch (Series 3), starting as low as under $200. This picked up a lot in 2019.

This has effectively allowed them to enter a new lower segment of the market while the series 4 continues to chomp away at the higher end consumer.

The "official" price of the Series 3 is $279. Or at least the price Apple pins its value at.
