#1: This is something different. I saw an ad in Facebook or something for a luxury watch with a movement similar to this one. I thought it was cool so I decided to create an interpretation it.
Three axles each with 4 hours to them. The three 4 hour groups rotate around the watch at 1/3 pie slice spacing. Each individual hour group axle rotates at the beginning of each hour as they impact the copper triangular striker in the bottom right.
Time is read off the bottom 1/3 of the watch. Minutes are along the bottom curvilinear scale. Hours are in the red circle pointing to the minutes. Seconds are the blue hand, also using the same scale as the minutes.
#2: In honor to the Nobel Prize in Physics for 2020 to Penrose, Genzel and Ghez, for contributions to the science of black holes. This is Ghez’s animation of the super massive black hole at the centre of our galaxy, Sagittarius A*
