Editor's Notes

Zenith's 'DEFY El Primero 21' watch has many of the same characteristics as the classic version from 1865, but this '21st century' design is updated with an intricate skeletonised dial and new movement. It has two escapements - one for the chronograph, the other for the timepiece itself - and features the maker's exclusive dynamic signature of one rotation per second. Manufactured in Switzerland from brushed-titanium, it has a sleek bracelet strap and sapphire crystal case back that reveals the automatic El Primero 9004 calibre 14 1/2" – a special detail that allows you to appreciate both sides.

We offer a two-year warranty for all working parts and manufacturing faults for luxury watches. For more information, contact one of our experts by emailing watches@mrporter.com
