But that all changed a few years ago when Zenith began reissuing many of its famed designs from the 1960s and 1970s.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003eThe El Primero was the culmination of a years-long research and development process undertaken by Zenith to develop the world’s first automatic chronograph movement. While other brands had sought to achieve the same feat — including Heuer (in concert with Breitling and Hamilton) and Seiko — Zenith intended to make the El Primero something entirely unique. Instead of taking an automatic module and merely sandwiching it onto the chronograph, Zenith fully integrated the two; moreover, the movement is a high-beat calibre offering significant added accuracy.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003eZenith announced the El Primero \u003cmeta charset=\"utf-8\"\u003e at a press conference on January 10, 1969. This was four years later than the brand had intended: It had begun developing the calibre in 1963, hoping to bring it out for Zenith’s centennial in 1965. Nevertheless, on that winter day in 1969, Zenith proudly displayed a working model of its chronograph.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003eThis El Primero Chronomaster Triple Calendar is one of the coolest complicated variations on the underlying movement design. Based on the caliber 25440 automatic movement, this Chronomaster flaunts a day, date, month and moonphase, all with the iconic automatic chronograph that made the El Primero famous. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003eThis pretty piece is set on a multi-link stainless steel bracelet with double butterfly clasp. The exhibition caseback gives a look at the movement, and all throughout, this piece bears details we don't see on any other Zenith. Something truly unique, this piece deserves a place in the collection of a discerning collector. \u003c\/span\u003e\u003c\/p\u003e","brand":"Zenith","offers":[{"title":"Default Title","offer_id":44580887003223,"sku":"40993500","price":5450.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0809\/1255\/files\/AS12754_40993500_ZENITH_ELPRIMEROCHRONOMASTER_02.0240.410--6-2.jpg?v=1793370436","url":"https:\/\/www.analogshift.com\/products\/zenith-chronomaster-el-primero-as12754","provider":"Analog:Shift","version":"1.0","type":"link"}
