The Unique One, is a limited edition desktop calculator developed using century-old Japanese Urushi lacquer strategy. To handcraft the body of the device, Casio admired none aside from Yamakyu Shitsuki, a lacquerware workshop expertising in the craft since 1930. Mater crafter Ryuji Umeda himself handcrafted the design involving a strategy called tamenuri, which took a month of refining. The craft involves layering laquer tree’s filtered sap on the milled aluminum housing and achieving a sense of depth with repeated applications over a duration of a week. Finally, the calculator is polished for that mirror-like shine and high-end feel.
Each of the 625 limited edition calculator’s is handcrafted carefully at the workshop, rendering every one of them distinct in their look depending upon the viewing angle. To bring the premium feel, the machined aluminum body housing the buttons on the top and the LCD screen guarantees a rewarding presence. This screen comes with a dual-sided AR finish for decreased reflections and the navy blue text color imitates the water fountain pen ink. For enhanced tactile sensation of pressing the isolation-type keys, they feature the pantograph system and an ergonomic shape nestling the fingers. The 3-key rollover tech ensures fast typing as the keystroke is accurately recognized for up to 3 keystrokes.
