One of Casio’s slimmest time pieces to date, the Poptone Cubic Puzzle Watch ($90) has a long case with a custom designed LCD display and buttons arranged at the bottom in a Tetris-like layout.

The rubber case and band make this a casual design but it’s functional too, with a stopwatch, alarm and date mode. With the added touch of an attractive animating display and patent white clasp, this is a modern design that you’ll love!
