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
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
Unveiled at this year's Baselworld watch fair, this new take on Cartier's Rotonde model houses the most advanced examples of the marque' watchmaking prowess. Featuring an Astroregulator, a minute repeater and an astrotroubillon, this hefty 45mm timepiece is limited to just 30 pieces.
With a ruby-capped crown, a space ship-shaped case carved from polished meteorite, an exposed tourbillon and a power reserve of between four to six days, De Bethune's Dream Watch 5 is like something from another world (perhaps because it technically is from another world).
