Design submitted by Logan from the USA.
This watch design is an analog 12-11-4 watch. There are three rotating disks that are painted white, bright red, and dark red, but are otherwise transparent.
The disk at the top shows the hours (1-12), the disk in the middle shows 5-minute groups (0-11), and the disk at the bottom shows single minutes (0-4). To read each disk, look at the disk’s color in the 9 o’clock position (in line with the black marks on the case). White = +0; bright red = +2 for hours and 5-minute groups; and +1 for single minutes; dark red = +1 for hours and 5-minute groups. Two bright red marks would mean 4 hours or 10 minutes or 2 extra minutes, and two bright red + a dark red would mean 5 hours or 15 minutes.
If you want an analog watch with a “wow factor”, this watch is perfect. The transparency of the disks and their different rotation speeds make the patterns displayed highly variable.
