Editor's Notes

Zenith revolutionised the fine watch industry with its first 'El Primero' timepiece in 1969 - 50 years later, it's still the world's most accurate series-produced chronograph. Housed in a 44mm brushed-titanium case, this automatic 'DEFY' reference has an impressive 50-hour power reserve and features a 1/100th second mechanism and two escapements - one for the watch and one for the chronograph. It's fitted with a tonal clasp-fastening bracelet strap and a sapphire crystal exhibition case back that reveals the intricate movement.

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
