What does apple watch series 7000 mean? Is it series 1 or 2?

Hi

7000 series refers to the aluminium material used in certain Apple Watch models including 1st generation, Series 1 and Series 2 models.

Some differences that you may find helpful to note include:

• Apple Watch (1st generation) models have a single core processor.
• Newer models - in the Series 1 and Series 2 ranges - have a faster, dual-core processor.
• Series 2 models also have:
  • A higher level of water resistance.

    The watch can be worn, for example, when shallow water swimming and is also more resistant to water than other models during general daily use.

  • A brighter display (twice as bright as 1st generation and Series 1 models).
  • Built-in GPS.

    This can be used to track workout route maps for certain outdoor workouts when the paired iPhone is not also taken along and can also be used to help locate a lost watch (subject to it being connected to a trusted Wi-Fi network).

• Aluminium models have Ion-X glass (these watches are lighter in weight than stainless steel models of the same case size).
• Stainless steel watches have a sapphire crystal, which is more scratch resistant than Ion-X glass.

All Apple Watch models are able to run the latest software (watchOS) version. You may find the following resources helpful when choosing an Apple Watch:

It is Series 0, the first generation of Apple Watch. On series 1 and 2 it say on the back exactly like that: "series 1" or "series 2". 7000, it is the name of the aluminium alloy.
