About the brand

Patek Philippe

Founded in 1893 by Antoine Norbert de Patek and François Czapek, Patek Philippe is recognized as the most renowned watchmaker in horology. Since 1932, Patek Philippe has been in the hands of the Stern family, and it remains one of the last family-owned watch manufacturers based in Geneva, Switzerland.

Patek Philippe has always been famous for its assortment of complicated timepieces, ranging from "petit complications” like annual calendars, chronographs, and world timers to "grand complications” like perpetual calendars, minute repeaters, and celestial creations. The impressive internal mechanical mastery of Patek Philippe timepieces is matched only by the fine craftsmanship of their exterior designs.

In addition to complications and grand complications, the Patek Philippe watch collection is also home to elegant dress timepieces such as the Calatrava and sports watches like the Nautilus and Aquanaut. It is the exceedingly popular Nautilus watch (and the younger Aquanaut that was inspired by it) that transformed Patek Philippe from a name recognized among seasoned watch connoisseurs into a coveted brand in modern pop culture too.

Compared to many other high-end watchmakers, Patek Philippe manufactures much fewer watches every year. It's been reported that fewer than one million Patek Philippe watches have been made since the company's founding. This limited supply adds to the value and collectibility of Patek Philippe watches and their rarity makes them even more desirable among collectors and enthusiasts.

Setting the watch

To wear

Crown Position 0 (crown screwed-down against the case)

To wear the watch, the crown is fully tightened against the case. When the crown is in this position, the Oyster Perpetual Day-Date is waterproof to 100 meters (330 feet).

To manually wind

Crown Position 1 (crown unscrewed)

To manually wind the watch, turn the crown clockwise. When setting the watch for the first time or after it has stopped, a minimum of 25 turns must be completed for partial winding.

To Set The Day & Date

- Crown Position 2 (crown unscrewed and pulled out to the first notch)

Turn the winding crown in a clockwise direction to set the date of the month, and in the opposite direction (counterclockwise) to set the day of the week. Throughout this process, the watch continues to operate.

To Set The Time

Crown Position 3 (crown unscrewed and pulled out to the second notch)

Turn the crown to adjust the hour and minute and set the time. The small seconds hand is stopped, enabling the precise setting of the time to the second. Move the hour hand to 12 o'clock to avoid a.m./p.m. confusion as the date changes at midnight.
