This is a very rare Pre-El-Primero Chronograph by Zenith, powered by a freshly serviced 146 D handwound movement. The 38mm case is in mint and absolutely unpolished condition (serial 185Dxxx). So is the original tritium dial with it´s color matching tritium handset. The hands in the contrasting grey subdials are a more unusual and rarer straight version as in most of the seen A279, but original to this watch as well. Natostar-crown, pushers and plexi have never been changed and are, as well as the whole piece, in mint condition. We offer this beautiful watch for sale on the original zenith/gay freres ladderbracelet with correct zb endlinks and on a black vintage sporttropic band with zenith buckle in addition.
