This year is a big year for Zenith manufacture celebrating 150 years. Along with other novelties from Baselworld 2015 that we have presented you here, we now bring you another watch released this last week, may we introduce the Zenith El Primero Chronograph Classic. The new Zenith El Primero Chronograph Classic features a pebble shaped case with a diameter of 42 mm and a quite slim profile at 12 mm thick. This new case —featuring a highly polished finish— comes with the nicest pronounced lugs— we've never seen before on any other Zenith El Primero— and with a very clean and timeless design that even includes a domed sapphire crystal. The watch is available in 18K rose gold in a limited edition of 150 pieces and in stainless steel as a regular production watch. The new Zenith El Primero Chronograph Classic is fueled by very strong Zenith DNA in its purest and most classic form.
