The Apple Watch Series 9 and the Apple Watch Ultra 2 were announced on September 12, 2023, during an Apple Special Event. Pre-orders opened that same day, with earliest shipping dates starting on September 22.

Aluminum case models of the Series 9 are available in Midnight, Silver, Starlight, Product Red as well as Pink, a new color for the line.

Stainless steel models are available in Silver, Graphite and Gold like the previous Series 8.

Both the Series 9 & Ultra 2 pack the new S9 chip which enables new functionalities like on-device offline processing for Siri, a new ultra-wideband chip to help you find a missing iPhone and Double Tap which recognizes when the user double taps their index finger and thumb together.

Depending on the screen, this can act as the primary button or scroll like the digital crown.

The screens on both devices have also been upgraded to boost the maximum brightness:

  • Up to 2,000 nits for the Series 9, double of the Series 8
  • Up to 3,000 nits for the Ultra 2, from 2,000 nits for the first-generation Ultra

Apple also announced that the Series 9 and Ultra 2 would be its first-ever carbon-neutral products (depending on the selected band).

SIM SIM (Subscriber Identity Module) is a small card that contains mobile network subscriber's account information. This allows the phone using the card to attach to a mobile network. The SIM card is most commonly associated with GSM and UMTS mobile networks. Moving a SIM card from one phone to another allows a subscriber to switch mobile phones without having to contact their mobile network carrier. SIM cards can also be used by a phone to store limited amounts of data, such as phone numbers and text messages. eSIM
