With the term avantgarde, we refer to a specific category of watches, i.e., those that adopt unconventional materials and design techniques, often combined with unusual time display. This category includes, for example, brands such as Richard Mille; some limited edition watches, primarily, feature advanced materials or technologies. Also, this category comprises collections from brands that are traditional but now include experimental models; take a look at a Luminor Carbotech™, for example.
