Perfume-Emitting Watch Tells The Time With Scents

Perfume-Emitting Watch Tells The Time With Scents

Fragrances matched to your circadian rhythm to guide you through your day.

The Scent Rhythm Watch by Aisen Caro Chacin could mean that you never have to look at your watch again when you want to tell the time. Instead of being aware of every second that passes, Chacin’s watch changes the way you perceive time by releasing a specific scent for different phases throughout the day.

Scent Rhythm maps fragrances in sequence with the body’s circadian cycle, which means each one corresponds to a specific state of being; which include waking up, being active, relaxing, and sleeping.

Olfaction and chronoception are both chemical senses, so I thought it would be interesting to map them onto one another


Each of four glass bulbs holds about a milliliter of unique fragrance. Every six hours, the watch releases the scent selected for that time of day, which could be coffee when it’s time to get out of bed, or chamomile when it’s time to sleep. The watch releases vapor like a mini-fog machine; a process which uses a piezoelectric atomizer and ultrasonic vibrations.

The watch is powered by a small lithium-ion battery pack inside which can be recharged via a micro-USB port on the wristband. One full charge should typically provide you with 24 hours worth of timekeeping.
