Price: $230,000 (165,000 EUR)
IWC Grande Complication IW927016IWC Grande Complication Ref. IW927016 consists of total of 659 mechanical parts, 71 of them jewels, twelve patents and 21 functions and displays, including a perpetual calendar for the next 500 years, together with perpetual moon phase display made of polished goldstone representing a star-stubbed night sky. Working inside the case are a chronograph and a highly complex minute repeater activated through an all-or-nothing piece slide.
This wonderful invention chimes out the time in crystal-clear tones, which are activated by the slide on the left-hand side of the case. Two tiny, precision-made hammers are released and chime the time in hours, quarters and minutes on two gongs. The striking mechanism is a technical tour de force. Initially, the chimes were inaudible outside the solid platinum case, so the glass was freely suspended on a platinum membrane to enable it to amplify the vibrations produced by the gongs via the sound transmission pin.
The case, too, finished in solid platinum with a fineness of 95 percent or 18 ct. rose gold, is first-class. Despite the complex design of the case, the Grande Complication is unaffected by superficial water splashes. Production limited to 20 watches per year.

A. Lange & Sohne Datograph PerpetualIn the Datograph Perpetual, Lange combines two classic complications - the chronograph (for short time measurements) and the perpetual calendar - in one landmark watch that is also enriched with many of the manufactory's acclaimed new-era attributes.
This masterpiece by Lange is the first wristwatch that incorporates a chronograph and a perpetual calendar. It no doubt represents the most classic combination of complications, capturing the moment, the present, and eternity. Additionally, it is endowed with all of the features that make Lange timepieces so distinctive. It owes its harmonious personality to the subtly offset symmetry of the solid-silver dial.
The Datograph Perpetual can stop times of up to 30 minutes with an accuracy of one-fifth of a second.
The movement is the automatic Caliber L952.1. The platinum case measures 41mm. When fully wound, the spring barrel of the Datograph Perpetual has a power reserve of 36 hours. The accuracy of the watch originates from a glucydur balance with eccentric poising weights, a Lange balance spring, and with a frequency of 18,000 semi-oscillations per hour. The watch consists of 556 individaul parts that must be assembled and adjusted to interact flawlessly in a time-consuming process.
