An image of the complexities of technology and the beauty of self-control, the Vacheron Constantin Patrimony Perpetual Calendar Ultra-Thin was first released in 2011. blue (2019) and slate gray dial (2017), the highest definition is the available gold color with silvery opaline dial. In keeping with the key design of the Patrimony team which also cites the design of the VC’s minimalist 1950s watch, the watch features the well-known Ultra-thin automatic caliber 1120 QP. Let’s take a closer look at this superb model.
Vacheron Constantin made the first endless calendar in 1884 (number 10155), a two-dimensional gold-pocket watch with 28, 29, 30 or 31 months. month, day of the week, months are a sign of the year jumping by day. By 1905, Vacheron had amplified the complexity of the timeless calendar by combining it with a repetitive minute and second chronograph. Although the nation developed handmade clock clocks from the 1930s, it was not until the 1980s that they were transformed into regular clock clocks with 43031 words followed the following year, in 1984, by skeletonized type (ref. 43032). . Relying on the extremely thin Jaeger-LeCoultre 920 ébauche, Vacheron Constantin turned to Dubois-Dépraz to help him with a timeless portion of the calendar that makes 1120 QP better. Still in use today but made in-house by Vacheron Constantin, this style is a short-lived vocal that lasts 48 months and a year of jump. To deal with all the problems of the Gregorian calendar (see box below), the standard calendar will not need to change until 1 March 2100.
Changing the calendar
The Gregorian calendar is a monumental beast and when English watcher Thomas Mudge decided to own a pocket watch that could know everything about the Pope’s calendar, he faced a daunting task. His mechanical engineer, completed in 1762, kept a period of months (28, 30 and 31 days) with an extension of every four years. in the leap year (29 days).
Pope Gregory was a little worried that the Julian calendar (founded by Julius Caesar in 46 BCE) would ruin 10 full days to disrupt important dates such as Easter, which were not in line with the weather. In order to bridge the gap between the Julian calendar and the solar year – the time required for the earth to revolve around the Sun – the pope enlisted astronomers in 1582 to correct the confusion and eventually agreed to increase 29.th day until February every four years. However, it was not straightforward like that. Aside from choosing dates in the church calendar, Gregory’s reform established the age-old law of answering the question of why 1700, 1800, 1900, 2100 and 2300 are. no years, but why 1600, 2000 and 2400 are years of skipping. According to the Gregorian evolution, each year divides exactly by 4 and the year equals. However, if a year can be divided by 100 (100 years) it is not a jump year… and leap year. This is why we who have the opportunity to live with an eternal calendar in our hands should remember to change the 28th of February 2100.

The fact that the dial is lightweight makes it look bigger than its blue and gray brethren, and it attracts more light.
In keeping with the refined atmosphere of the 1950s Patrimony collection, the clock handles used are made of pink gold and are followed by a small ‘pearl’.

The shortest case length is possible due to the very thin motion – caliber 1120 QP – based on the legendary 1120 1967 legend with a length of 2.45mm.

Now house-built by Vacheron and certified by Hallmark of Geneva, the integration of the QP segment results in a height of 4.05mm.
