So I emailed CTDI and US sets are covered under warranty here in Singapore. Very tempting to get one Bay 512 GB from the US during the black friday deals.
"Regarding your inquiry, please be informed that after further checking with our relevant department, we would like to inform you that the warranty is covered in Singapore for the Pixel 8 Pro which was purchased from US.
Pertaining about the warranty of your Pixel 8 Pro, kindly be informed that it is covered under warranty within one year based on the purchased date which it is stated on your proof of purchase (POP). Please take note that your device should be in good condition (Physically) before you bring it to us for claiming it under warranty because the warranty from GOOGLE will be void if there is any physical or water damage on the device."
