These are all models that Apple advertises as "carbon neutral", a designation introduced in September 2023 with the arrival of the Series 9 and Ultra 2, and one that was added to the SE 2 launched the year before.

Apple customers filed a class action lawsuit against the company, alleging it misled consumers with claims that certain Apple Watches are carbon neutral. For a product to be considered carbon neutral, its manufacturer has to offset or cancel out any pollution the item generates.

In a complaint filed on Wednesday, seven purchasers said they would not have bought their watches or would have paid less had they known the truth.
