Citizen has been making some serious waves this year through their Promaster collection. But let us not forget that Citizen is a brand that produces more than your robust, and at times funky, sports watch. Since 2016, Citizen has been the proud owner of the thinnest analog, light powered quartz watch in the world called the Eco-Drive One. Last week, Citizen released five new watches that builds out the Eco-Drive One collection, providing a new range of options to add an ultra-thin watch to the quiver.
The Eco-Drive One houses the Citizen Caliber 8826. The movement is made up of 85 individual parts, most of which are designed by Citizen themselves, including a two-component rotor as opposed to the traditional three-component rotor found in most watches. The result is a movement that measures a slender 1mm. In addition to the Caliber 8826, Citizen maintains the slimness of the Eco-Drive One by utilizing a ring-shaped solar cell that is placed on the same plane as the gear train for the hands. Combine the former with a 3.7 volt rechargeable cell developed in collaboration with Hitachi Maxell that measures just 0.87mm thick, the Eco-Drive One is a watch that looks to hold its title for the thinnest analog, light powered quartz watch for the foreseeable future.
