Editor's Notes

Zenith's 'Defy El Primero 21' watch houses the most precise series-made calibre in the world - nine months of meticulous craftsmanship go into the making of each one. The movement, which dates back to 1969, is on view through the skeleton dial and exhibition case back of this ceramic and rubber edition, as is the special star-shaped satin-finished oscillating weight. Engineered with two escapements (one to power the chronograph functions and another for the timekeeping), it has small seconds-, 30- and 60-minute counters along with a central hand that turns once per second and an indicator at 12 o'clock to show how much of the impressive 50-hour power reserve is left. The textured-rubber strap fastens with a resilient DLC-coated titanium clasp. We offer a two-year warranty for all working parts and manufacturing faults for luxury watches. Call our Customer Care team for more information.
