More commonly marketed to women, are we about to see a resurgence of square watches for men? If so then Longines is ahead of the curve, writes Chris Hall

When you think about it, there are plenty of logical reasons for a watch to be round. The mechanics inside a movement operate in circles, from the unwinding mainspring that drives the watch to the wheels and gears that translate that energy into regular, controlled motion. It’s easiest to read the time on a circular dial, with every point equidistant from the centre, and at a deeper, more fundamental level, the building blocks of our system of measuring time are all approximately circular: the rotation of the earth on its axis around the sun, and that of the moon around the earth.
