Casio CA-53W Calculator Watch

There’s a calculator hiding in plain sight below the time.

Casio gave every digit a key and squeezed the whole keypad onto a watch face. Tap a few buttons to divide a dinner bill, then switch back to the time. The little arithmetic signs are printed between the rows, right where your fingertip needs them.

WHY IT CAUGHT OUR EYE

The keypad makes sense as soon as you see it. It is also small enough to make working out a tip feel like operating a miniature control panel.

BEFORE YOU BUY

The small keys suit occasional sums better than a long column of figures. This black version has dark digits on a light display.

One black resin CA53W-1 with a light LCD and dark digits. The listing gives CA-53W-1ER as its model number.
