Casio has unveiled a limited-edition calculator, the S100X-JC1-U, dubbed The Special One. Priced at $630 and limited to just 650 units, this premium calculator blends exceptional craftsmanship with practical features aimed at enthusiasts and collectors.
The calculator features an aluminum chassis finished with a glossy black lacquer, carefully applied by hand using traditional Japanese techniques. Red highlights accentuate some keys and the front panel, while button markings are stamped in gold, emphasizing exclusivity and refined design rarely seen in calculators.

Casio uses an FSTN (Film Super Twisted Nematic) display, known for higher contrast and lower reflection compared to typical calculator screens. The display shows dark blue digits on a nearly white background, improving readability in various lighting conditions-an upgrade appreciated by users who rely on clear, precise visuals.

The keys are equipped with a scissor-switch mechanism, commonly found in laptop keyboards, to deliver consistent tactile feedback and uniform pressure no matter where the key is pressed. Additionally, the calculator supports three-key rollover, allowing it to accurately process rapid input without missed keystrokes-a feature valued by power users.
Key specifications and pricing of Casio The Special One:
- Weight: 275 grams
- Battery: Single CR2025 with up to 7 years of life based on one hour of daily use
- Limited edition: 650 units
- Price: $630
While the $630 price might seem high for a calculator, the combination of meticulous craftsmanship, advanced display technology, and long-lasting battery justifies its premium appeal in a niche market.
Casio’s move to target calculator aficionados with luxury touches recalls how other brands have elevated basic tools into collectible items. Whether The Special One will set a new trend for premium calculators or remain a unique collectible, it certainly adds flair to a traditionally mundane gadget category.
