Inspired from the legendary β€˜Rotary’ engine, “ROTARY” Series is an automatic wristwatch with a unique design of time display. From which we took the iconic Rotary engine as this project concept. From there we took the motions of the engine rotors and turned them into display for time in ‘Minutes’ & ‘Hours’. By mean of such we have made use of the twin rotors system and turned them into hours and minutes indicators while the unique β€˜Rotary’ engine rotor running track has also allow us to create a unique time display.

“Rotary” is a mechanical wristwatch which we have constructed base on a β€œETA” caliber 2824-2 Swiss automatic movement as a power source. From there, we have designed and constructed a twin-rotary construction module on top which simulate the motion of the iconic Rotary engine. The large rotor with the triangular pointers rotating with a fixed but non-uniformed track at the bottom alongside with the applied metal indexes on the left-hand side of the dial will represent the time in β€œHOURS”, whereas the smaller triangular 3-pointer rotor on top alongside with the metal applied indexes on the right hand side of the dial will represent the time in β€œMINUTES”. (Both rotors are installed with sufficient numbers of rubies for reducing friction and to increase efficiency.)

The dial and the rotors do come with luminous to show time in the dark. The dial has been skeletonized so that the mechanism can be clearly seen.
