Not likely. There is a video of each of the picc ports sliding down his arm independently. Watches don't do that.

Most likely a medical device of some kind, picc port would be the best guess, installed as an alternative to the venous stick that has been spotted on his hand.
I’m going to say here and now there was no wireless communications device of any kind. If proven otherwise I will admit aI was mistaken, but it is too risky and damaging if discovered, too easily foiled, and of minimal value in this setting. There are no obvious instances where Biden was distracted by aural prompts or where his answer reflected some fact that had been relayed to him. His mental condition is not conducive to multitasking or smoothly pivoting to incorporate new data. VerbAL prompts would have thrown him off into never land for sends, he no longer has the capacity to operate that way, if he ever did. The one thing he has come by honestly is his reputation for being dumb.
Instead they armed him with two basic fallback lines: Trump is a liar, what he says is not true, and that he failed and has no plan. Count how many times those two ideas were expressed and it would total 2/3 of Biden’’s speaking time.
