ABSTRACT:
The present invention includes a dual display watch module comprising a watch face with selectively changing backgrounds which is capable of displaying the time of day using an analog display superimposed over the color-changing watch face thereby creating unique optical effects and patterns and which has a significantly reduced overall thickness. The invention includes a novel configuration of the internal components of the timepiece resulting in a significant reduction in the thickness of the subject timepiece, thereby enhancing the comfort of the individual wearing the timepiece. The novel configuration comprises positioning two smaller sized batteries in the same spatial plane as the PCB and analog watch movement instead of the conventional stacked assembly arrangement whereby a larger battery is placed directly behind the PCB. This allows for an overall thinner movement, thereby resulting in a significantly thinner watch without detracting from the functionality of the watch. The novel configuration of the present invention is achieved by utilizing a single micro-control unit (MCU) to drive both a core analog movement and a color-changing LCD display. Utilizing two 1.5V batteries, the present invention continuously powers the analog movement at 1.5V and steps up the voltage to 3V to intermittently power the color-changing LCD display.
