The B.Zero1 102320, seen from the bench

The Bulgari B.Zero1 (Ref. 102320) is a two-tone watch in pink gold and steel with a 23mm case, featuring an integrated sculptural bracelet inspired by the Colosseum's spiral. Custom strap work by Atelier Casati Milano adapts premium leathers—Swift rose, Barenia honey, Mississippi alligator—to the case lugs while respecting the original design's architectural integrity.
