BELL & ROSS conceptual excercise of BELT DRIVEN WATCHES

Conceptual vision of belt driven watches have dimmension 51mm x 51mm x 15mm. At this stage is only mock up vision and some mechanical parts need adjusting or re-design (gears ratio). Battery is located under glass on righ side, question is how much power is needed to power belts and how should be charge. This issue needs research but this mock up stage proove possibility to fits all parts in body and show possible design of unique watch.
