In the context of that era, it is important to note that quartz watches were not complicated. They had become popular because they offered unfailing accuracy at a low price. Mechanical watchmaking was dominated by complications, and the perpetual calendar in particular. Jean-Claude Biver, who worked at Panerai Luminor Chrono Replica in the early 1970s and later founded Blancpain to promote complicated mechanical watchmaking, was not unaware of this lesson. If we could travel back in time,Panerai Replica Watches it would be interesting to ask Rochat, Golay, and Berney, "Why the perpetual calendar?"

Let's take a moment to define what a perpetual clock is. We have a four-year leap year cycle because the solar year is shorter (365.25). This means that we accumulate a small amount of debt each year, and every four years this is compensated by adding an extra day. The 29th February.

You can get more technical and say that every 100 years the leap year is not included because it creates an extra minute. A perpetual calendar is a watch that shows the date, day and month of the year, as well as the phase of the Moon. Perpetual calendars have become smart. They are like Asian mothers: they're always right. If they were border collies, they'd be MENSA-qualified dogs capable of solving complex algorithmic problems, composing haiku poems, and singing Verdi operas in phonetically perfect Italian while shearing sheep. Why?

They can automatically compensate for the shift in the 30/31 rhythm and also account for the 28 days of February.
