I’ve seen so many people commenting about Scotty’s watch as if it was some epic new thing only present in Beyond, so I’m going to have to point out that he’s been wearing it all along, not only in 2009 but also in STID… :P
If you rewatch them looking for it, you will spot it several times.
In 2009 it’s hard to see while he’s in his winter clothes, because of so many layers, but you see it might be there peeking out sometimes:
You see it best when Scotty is manning the transporter later in the movie:
And again in STID, on various moments, such as during the Space dive:
And later while the Enterprise is going down:
So now we can wonder whether the watch will survive the events of Beyond, but it certainly isn’t a new prop for Beyond only… :D
