Zenith Sporto from the early 1970s
A restrained Sporto from Zenith’s early 1970s output, presented in a 36 mm stainless-steel case with a striking original blue sunburst dial and applied baton indices. The period-correct acrylic crystal and star-signed crown underline the watch’s original specification. At its heart sits the manual-wind cal. 2562C, a 17-jewel movement freshly serviced in 09/2025. For a modern collector this Sporto offers wearable proportions, clear period character and a well-documented service history, making it an appealing daily-wear vintage piece that respects its mechanical origins.
