Here we celebrate those watches at the most complicated, artisanal, expensive and downright nutty end of the timekeeping pool – some of which take years to make.More
About as futuristic-looking as minute repeater timepieces get, Audemars Piguet's Concept Supersonnerie (released last year) would give even the most mellifluous chiming pocket watches a run for their money in the sound stakes. With a titanium case (designed specifically to minimize sound absorption) and a tourbillon thrown in for good measure, this is perhaps Audemars Piguet's most impressive release in recent years.

Commissioned for Marie-Antoinette by a secret admirer in 1783, the No.1160 was the most complicated watch ever created at the time (it wasn't finished until 1827 - some 34 years after her death). Now, the timepiece has been immaculately replicated. Comprising 823 parts, there's a display showing the difference between civil and solar time, in addition to a chronograph, a power reserve indicator and a bimetallic thermometer.
The timepiece is not for sale but was estimated to be worth USD 30 million in 2013, breguet.com
