Nikon has a patent for a smart watch that emits fragrance | Nikon Rumors
The purose of this watch is quite clear. First it emits a choice of pheromones to attract various wildlife during mating season to capture that once in a lifetime shot.
Another use is the watches ability to spray at push of a button, ones favorite parfume or cologne (depending if Nikon shooter is female or male) while shooting on the sideline of a sports event to attract the teams pro superstar to accept offer for after event dinner and drink and exclusive photo shoot.
Of course third option is a short spray of mace which may be userful when being chased down the street by a umbrella wielding individual after an episode of taking their photograph without permission during a day of street shooting.
The possibilities are endless. I just hope they incorporate wifi/bluetooth option so dedicated button on camera can activate choice of watch's spray by a simple quick push . What will Nikon come up with next with todays limited R&D funding?
