What is a key feature of a triple calendar watch compared to a perpetual calendar?

A triple calendar watch is typically less complex and costly than a perpetual calendar watch. This distinction arises from the functionality and mechanics behind each type of watch.

A triple calendar watch displays the day of the week, the date, and the month, requiring manual adjustment at the end of months with fewer than 31 days. It operates using a simpler mechanism that tracks these three aspects of time while it does not account for leap years.

In contrast, a perpetual calendar watch is designed to automatically adjust for varying month lengths and leap years, making it significantly more complex. This complexity often involves sophisticated gears and additional functions that contribute to its higher cost and intricacy.

This fundamental difference in mechanical complexity highlights why the triple calendar is regarded as less complex and more affordable, aligning directly with the notion of it being less costly than its perpetual counterpart.
