In 2013, Arnold & Son managed the incredible feat of creating a super thin tourbillon watch called the Ultra-Thin Tourbillon Escapement, or simply, the UTTE watch. The watch was just 8.34mm thick, while the movement itself was a scant 2.97mm thick. Though it has lost the title of the world’s thinnest tourbillon watch to the Bulgari Octo Finissimo Tourbillon, that hasn’t stopped Arnold & Son from improving its UTTE watch. Earlier this year, they debuted the Arnold & Son UTTE Skeleton watch, which claims the title of world’s thinnest skeleton tourbillon watch.
Creating an ultra-thin watch is no easy feat. First of all (and obviously), there’s the difficulty of manufacturing components to be as thin as they can possibly be. Secondly, and perhaps more importantly, there’s the need to ensure that while the watch is as thin as it can be, reliability and practicality are not adversely affected. As the watch and its components become thinner, they can also become less sturdy and resistant to outside forces. In other words, they might be more susceptible to being flexed and damaged.
