Design submitted by Sam from Germany.
Sam had two ideas combined in this watch. One was about placing the display on an edge facing the eyes of the wearer and use the free space on top of the wrist for a battery recharge mechanism. Another idea was about having a tilt sensor and the fun you can have with it. The result is this tilt sensitive watch concept with manually rechargeable battery.
The time display: It has three display modes with different difficulty. Red LEDs are for the hours, green for 10 minute steps, and blue for single minutes. The LED rows start from the left and grow to the right. You just have to count the LEDs. In easy mode, the three colors are aligned separately. In medium mode, the colors are partially overlapping which creates confusing but cool looking mix colors. In difficult mode, the colors are overlapping completely.
The tile mode: You have to press a separate button to enable the tilt sensitivity mode. You can set the amount of sensitivity with the setting button. Once you press the tilt sensitivity button, the current orientation of the watch is saved and is considered as “0,0,0″. Any rotations in the x-, y-, and z- axis are shown now by red, green, and blue LEDs. Since no one makes perfect moves, many LEDs will light up and light colors will mix depending on the display mode. So whatever you do, the display flickers and flashes in different speed and colors.
The energy: To compensate the vast energy needs, you have to use the charge slide on top of the watch. Sliding creates a rotation in two internal generators which create energy that it saves in a battery. If you slide once, the time shows up. If you slide at least five times, the display shows a battery charge bar.
The secondary battery: Besides the manually chargeable battery, there is a small battery which powers the watch memory. So if your main battery is empty, the watch still knows the time. Just slide a bit and you know it, too.
The tilt log: Each rotation of the watch is recorded for 24 hours. So even if your display is not in tilt sensitivity mode, the log saves your moves. At the end of the day, you can download the log on your computer (USB) or smart phone (bluetooth) and analyze it.
This watch is for party people, statisticians and geeks in general. It is a watch with a high fun potential. The ever changing display and the manual recharge mode are pretty outstanding.
