In the below image you'll see an annotated Q drop.
The first thing interesting to note is the "delta". This Q drop was originally posted on Dec 15, 2019 - a one year delta from today. Next this drop (3689) has a "quote post" from another anon which was a screen shot of a tweet that shows a watch Q has posted in the past with the time at 1:29. The annotated part is someone saying look at these three important things that happened at 1:29 which is the same time of the watch Q posted.
