It established a new standard of precision in mechanical watchmaking. Beating at 5Hz,  36 000 vibrations per hour, and capable of measuring 1\/10th of a second, the El Primero became the technical foundation of the Maison’s identity.\u003c\/span\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003e\u003cspan\u003eAt Watches and Wonders 2026, ZENITH unveils a new expression of this legacy: the CHRONOMASTER Sport Skeleton. Through its openworked architecture, the Manufacture reveals the mechanical complexity of its most emblematic calibre while introducing a new patented folding clasp, a new ergonomic development reflecting ZENITH’s holistic vision of performance, where movement engineering and functional innovation evolve together.\u003c\/span\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan\u003eWith the CHRONOMASTER Sport Skeleton, ZENITH pushes this mechanical expression further by bringing the movement to the forefront.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan\u003eThe sapphire dial subtly tinted from black at the periphery to transparent at its center, reveals the openworked architecture of the calibre beneath.
