Corrected entry: When Ben Affleck is figuring out where he sabotaged the machine, he says there are only two things left in the envelope: the bullet and the crossword puzzle. Why didn't he consider the watch on his wrist? He had no idea what it did, and it hadn't triggered yet.

Correction: Mike already assumes that the watch has been 'used' since it was taken out of the envelope in the beginning by the FBI agent and put on his wrist. The watch had a double purpose; identifying that the contents of the envelope was his (the tan lines matched), and warning him to 'go'. Even though it's second purpose hadn't been served yet, it's assumed that anything outside the envelope shouldn't be needed anymore, therefore he wouldn't second guess this.
