Jordan Kahn, 9to5Mac:
Apple appears to be running low on inventory for Apple Watch Series 3 repairs as the company informed store staff today that it will substitute some Series 3 repairs with the newer Apple Watch Series 4.
And:
The change means that customers looking for a repair or replacement for their Apple Watch Series 3 Stainless Steel (GPS + Cellular) model will instead be fulfilled with Apple Watch Series 4, Stainless Steel (GPS + Cellular) inventory as a replacement due to constraints on the older model.
Good to know. Huge swing in satisfaction, going in to the Apple Store all sad with a broken Apple Watch 3 and walking out with a brand new Apple Watch 4.
