Steel , industrial plants , engines , machines, wheels - the universe and the design of Sevenfriday are heavily inspired by these elements. The final product is the result of this inspiration, combined with a high-tech manufacturing and construction extremely complex. A fusion of contrasting materials and style. The Sevenfriday P3 are built from two basic elements , the casing and the interface . The first , made of steel, of a clear industrial inspiration , is constructed in a complex manner and serves to protect the chest , in turn surrounded by a ring of aluminum . The casing is the interface, which consists of discs and hands , dial and movement . The indices are designed and arranged so as to bring the complexity of the movement on the surface . The dial is made &8203;&8203;up of 5 separate elements placed on multiple levels, with eleven different functions . The variety of materials , finishes and colors complete the uniqueness of the collection , the red details on the dial, in stark contrast between the black accents and dark gigio housing and interface , make the P3 aggressive, dynamic and powerful.
