Citizen Carry V4
Brief History
After Citizen’s previous hand-sized calculators, mostly operated with rechargeable batteries, the first true pocket-sized models launched in 1975, were branded Carry. These were initially manufactured by Omron, but later Citizen distributed some types made by smaller, less known japanese companies. The Citizen version of Omron's Ginkgo-leaf-shaped model 88 was made in a brilliant red color, which, in addition to its unique design and excellent material quality, made it a very popular design object.
