Introduced by Zenith in 1972, the El Primero Ref. 01.0200.415 was produced in a limited series of 4950 examples. Only in production for a mere 6 years before being replaced by the Ref. 01.0201.415 with ‘black dial’ counting 50 pieces, the present watch has become a highly sought after vintage Zenith watches.

Also called ‘The Big Blue’ or ‘TV Screen’, this chronograph features a squarish-tounneau, masculine and robust oversized 42mm stainless steel case. Zenith advertises the Ref. 01.0200.415 as “A new elaborately styled model with larger, easy to use press levers, replacing the usual push buttons”. In fact there’s a single piece of steel that function as a lever when activating the pushers.

The watch was sold with an integrated stainless steel bracelet that starts at 31mm wide at the lugs and tapers to 16mm at the clasp, adding a nice level of comfort on the wrist. Zenith used two different bracelets for this model. The earlier examples, like we have here, had a thicker, heavy style of bracelet, dual signed at the clasp with both the Zenith and Châtelain logos.

Offered in excellent condition, this present timepiece is a fantastic opportunity for vintage Zenith collectors to add a beautiful specimen of the rare reference to their collection.
