This is an original and rare Heuer ref. 3147 1960s measuring 35mm and housing a recently serviced (accurate) caliber 189 chronograph movement by Landeron. The original black dial and baton-style handset look amazing for its mid-’60s age. The lume is original. This watch displays stellar condition and appears to have not been polished. This watch comes with a rare vintage Heuer signed buckle. We installed a tropic strap to complete the look. This is an amazing opportunity to own this classic and rare piece displaying excellent overall condition for its age. Please make certain you enlarge the photos for detail.
