In Spectre, Q hands James a watch. Asking what it can do, he responds "It tells the time." A nice pun in what's also an ad for the Omega Seamaster 300.
In cinema, before the movie started, they actually showed that ad, which was somewhat disturbing, like seeing the trailer of a movie right before the movie. Maybe this biased my attention when the scene showed up in the actual movie.
in a car chase, James finds out that some of Q's accessories aren't that useful. Possibly Q did a half-hearted job on it because of what was supposed to happen to MI5 and the 00 agent program.
that means James knows that before the scene of interest to my question occurs:
being strapped to a chair James is tortured by
OberhauserBlofeld and after some time activates his watch which happens to be an explosive to escape.
I couldn't really tell if James is doing that intentionally, doing it intentionally but slowly to avoid attention or if he's merely finding the additional meaning of "it tells the time" by accident/luck.
The whole scene wasn't very convincing to me. In retrospect, maybe that's because the line "it tells the time", is some in-universe reference? There are a lot of references to other James Bond movies in this one. Did I miss anything? Did James know all the time that he could do what he did the way he did it?
I understand that part of the plot of a spy movie is to pull out surprise solutions to problems, but this one appeared to be surprising even for the spy.
