The Chronometre Observatoire Only Watch 2015 is a piece unique created for the Only Watch Auction. It features an aluminium case and dial; as if not rare enough, the bridges of its L200 movement are also made of aluminium.Despite its unusual aluminium movement plates, the present watch is one of the first of the ‘new’ Leroy (no longer L.Leroy) watches to be made commercially available.
