Bvlgari Octo Finissimo Perpetual Calendar Tantalum for Only Watch

A world record. An extremely rare metal with a bluish grey colour. A one-of-a-kind creation. For its first participation in Only Watch, Bvlgari has created the Octo Finissimo Perpetual Calendar Tantalum.

Only Watch, a watch auction that supports research into Duchenne muscular dystrophy, consistently gathers the exceptional in terms of brands and unique creations. For its first participation, Bvlgari is upholding this tradition with the Octo Finissimo Perpetual Calendar Tantalum.

This one-of-a-kind model reflects the characteristics of its predecessors. A Manufacture movement offering the most magical complication of all: the Perpetual Calendar, embodying mastery of all the calendar-related facets of time until February 2100. Launched in 2021, this seventh world record has so far been housed in a titanium case as well as a platinum case measuring 5.8mm thick.

For Only Watch, however, Bvlgari has chosen one of the rarest metals endowed with special and unique properties: tantalum. Highly resistant to corrosion and totally biocompatible, it is used in medical engineering, the nuclear industry and electronics. Its density is 16.6 g/cm2, making it twice as heavy as steel. The material used by Bvlgari for the Only Watch is of absolute purity, verging on 100%.
