Looking for a High-End Watch? Think Square.

Circular watch faces may be the standard, but who ever said standard was the only way to go? If you're looking for a new high-end watch—one that stands out, but does it with subtlety—a squared-off timepiece might be exactly what you need. And thanks to trustworthy secondhand sources like Crown & Caliber, you don't have to rely on the vagaries of the market at any given time. Instead, you can shop around for newer and older styles at once, and pick what you like best.

The shapes themselves run from slightly curvilinear rectangles with softer corners to, well, actual squares. But what brings them into the same family is a bit of geometrical edge that makes them feel markedly different than your everyday watch. And the pieces themselves—whether it's the newer Tetra from German brand Nomos or a classic like the Jaeger-LeCoultre Reverso—are the kinds of things you'll be happy to have someone notice and ask about at the office or on the street. Here are five of our favorites to buy right now.
