How soon can Apple Watch see the chat history?

How soon can Apple Watch see the chat history of WeChat? It can be kept for seven days.

Iwatch WeChat records can only be saved for 7 days, and only one chat record can be maintained at the same time. If it is newly uploaded, it will overwrite the previous chat record. If you forget your password and can't get it back, you can only upload the chat record again, and you need to reset your password every time you upload it. If you don't clean it up, iwatch's chat record will be kept until it is cleaned up.
