That’s both true and not. Yes, it’s true that once clock makers started adding dials they used clockwise because they mostly lived in the northern hemisphere, and decided to mimic the design of sundials. What’s less obvious is the inclusion of dials at all. While in popular imagination the road from sundial to clock is clear, in reality some of the first modern clocks had no faces at all. The initial responsibility of medieval clocks was actually chiming, first in “liturgical hours” and then eventually regular hours. Their weight, cost, and inaccuracy meant that they were more commonly used to call monks to pray (hence liturgical hours) than for economic activity. Jumping from chiming to circular clocks was actually a pretty significant leap for clock makers, and one that only seems obvious in retrospect. Especially since sundials typically trace semi-circular paths and not the full circle that a clock uses, and the installation of clocks into tall, prominent locations took a few centuries.
