About this reference
The Zenith x Voutilainen x Phillips Unique Piece Calibre 135-O was produced in 2022 as a singular execution for the Geneva Watch Auction: XVI. This reference is valued for its historical movement, a 1950s-era Calibre 135 Observatoire chronometer movement restored and decorated by Kari Voutilainen. Unlike the limited edition of ten pieces in platinum, this unique piece features a 38mm case constructed from niobium, a rare refractory metal. The dial is made of guilloché-engraved blue gold with a matte finish and features a large sub-seconds register. As a unique piece, it does not have a standard secondary market price range, but it achieved a final sale price of 315,000 CHF at auction in November 2022. This specific reference represents the only time a vintage Zenith observatory movement has been housed in a niobium case for public sale.
