I've seen him with an Omega AT as well ~ during an actor's roundtable.
As well, my wife took care of him at NYU Medical Center in NYC, back when we lived there -- around 2006/07, and he was wearing (her words) "a Blank Pen or something like that... does that ring a bell? It had a pretty black ring around it with numbers."
Ahh, yes honey it does. 😉😁
