Fragrance is powerfully connected to our memories of certain people, places and times in our lives – and this unusual concept watch takes advantage of that fact in order to tell the time of day. The Scent Rhythm Watch by Aisen Caro Chacin releases a particular scent every six hours, mapping the fragrances to the body’s circadian rhythms.
Each scent corresponds to a particular state: waking up, being active, relaxing and sleeping. The idea is that our bodies will remember what each scent ‘means,’ and begin to go into the correct state as soon as it’s released.
The watch features four glass bulbs, each containing one milliliter of a unique fragrance. Theoretically, those bulbs could be filled with any fragrances the wearer likes, but the designer has chosen scents from Demeter that correspond quite fittingly to each period of the day: Espresso for the morning, Paper/Tarnish for the daytime, Tobacco for the evening and Chamomile for night.
The watch runs on a rechargeable LiPo battery and uses an Arduino Pro Mini microcontroller board to time the release of the fragrance.
