Apple Watch Ultra 2 can read blood oxygen levels in countries where permitted. Apple Watches sold in the US after January 18, 2024 do not perform blood oxygen level measurements. Those sold before that date still perform the function as they originally did.

LL/A has a functional Sensor and LW/A was made available after January 18, 2024 and does not measure blood oxygen levels.

Thank you, and what is the index of the models for the American market, LL/A or LW/A?
