Is there a slowdown in the watch industry? You wouldn't think so when you saw the new watches that the brands introduced during the SIHH. From complicated skeleton watches to understated dress watches, it was all there and everything in between. We picked out 10 favorites.

A true magician can show you nearly all of its trick, and you still have no idea how it works. The same can be said for the Rotonde de Cartier Mysterious Hour Skeleton Watch.

By Martin Green Ever since its introduction in 2008, the Fine Watchmaking Collection has been Cartier's calling card when it comes to complicated pieces. Many of them unique and never done before. For the SIHH 2017 Cartier is expanding the collection with new models, as well as some varieties of existing models. It is not a surprise that many of them are focussed on the brand's unique, mysterious movement, that has become one of the pillars of the Fine Watchmaking Collection.
