Zenith El Primero Chronomaster — High-Beat Chronograph in Blacked-Out Titanium

A commanding interpretation of Zenith's most storied chronograph, this El Primero Chronomaster pairs a 45mm titanium case with a stealthy PVD/DLC coating and a black dial. It is a watch built for those who value engineering as much as presence, offered here pre-owned in near-mint condition.

At its heart is the El Primero 4061 automatic movement, a column-wheel chronograph beating at 36,000 vibrations per hour (5 Hz) — the high frequency that lets the El Primero measure short times to a tenth of a second. The caliber carries 31 jewels and delivers roughly 50 hours of power reserve, and its finishing is visible through the sapphire display back.
