The dial and case show some visible signs of the passage of time and that’s just the way we like it. The classic two-register chronograph is, thanks to its amazing condition and slightly larger-than-normal-for-vintage size, immensely attractive. The movement is Zenith caliber 156 – column wheel, lateral clutch – and again, the quality here is exceptional. The steelwork is all straight-grained with beautifully beveled edges.Simply a stunner inside and out. That any collector would want to have in their collection.
