The flagship S100X turns what could normally be considered a ubiquitous business tool into a head-turning conversation piece. The S100X is the result of Casio's pursuit in combining luxurious aesthetics with computation. The calculator features a shaved aluminum alloy body with a contrasting diamond-cut border treatment. The S100X is fully seated on a rubberized platform for maximized stability. Keys on the S100X feature a slight concave surface to conform to the finger that will perform linear, smooth keystrokes.
