All the other watches posted had the date on which they were posted as the date on the watch. Only this one had the date 19, and was posted on the 27th, IIRC. Which is why the date is important on this one, but not the others. This is also the only watch post that hasn't had a solution yet.
Thanks. I will have to go back to the Q drops with watches and answers. I’m slow at puzzle type things.
