The AT0797-01E is an Eco-Drivechronograph from Citizen’s July 2009 collection. This one was Citizen’s first attempt towards incorporating more-than-one newly developed technologies that flaunted through enthralling timepieces.
The first one is definitely Eco-Drive converting light into electrical energy; the other one is a high performance chronograph mechanism (59 minutes in 1/59 increments). It’s both hardy and stylish withadd-ons comprising a tachymeter bezel, a calendar (magnified date view at 4’o clock) and a 12/24 tracker. This is particularly helpful in setting the date and its changing schedules. You’ll know how once you purchase it, don’t worry.
