Never the wrong date again!

Have you ever wondered why you have to set the date on your wristwatch regularly?

Basically, for a wristwatch, a month always consists of 31 days. This is due to the fact that under the dial is the so-called date disc. On this disc the numbers 1 - 31 are listed. When the watch completes a 24-hour cycle, the date jumps one digit. It always does this strictly from 1 - 31, regardless of the month. The clock does not automatically recognize if a month has 31, 30 or even only 28 or 29 days. So the date has to be set manually at the beginning of a month.

The date must be reset on the 1st of each following month:

- March

- May

- July

- October

- December

Are there wristwatches that always show the date correctly without me having to reset it every now and then?

There are such wristwatches, yes. For example, most smartwatches and digital watches always show the correct date automatically. However, the most interesting type of watches that display the date correctly are mechanical watches with a so-called perpetual calendar. A perpetual calendar is one of the supreme disciplines of watchmaking. The mechanics and production are accordingly complex. Only very few manufacturers are able to develop and produce mechanical watches with a perpetual calendar. These watches always show the correct date even in leap years. In addition, there are watches with a four-year calendar, where only in leap years the 29th of February is not correctly recognized. Mechanical watches with four-year calendar and perpetual calendar are usually very expensive and therefore not affordable for everyone.
