Radiation Level LED Watch Design
The nuclear themed display shows hours 1-12 across the bottom, groups of 5 minutes, 5-55 in the top left section and four single minutes in the radioactive symbol in the top right. The effect is something that looks like a display for measuring radiation levels.
The case of this watch design is laid out asymmetrically creating an industrial appearance and is finished in black. The design has a charging indicator so would presumably be a USB rechargeable watch. The design has an animation which can be viewed in video below.
