Chronomaster Open Steel Watch 03.3300.3604/69.C823

In this ref. 03.3300.3604/69.C823, Zenith bypasses the traditional solid metal face to show you the high-frequency mechanical engine doing the actual heavy lifting. Part of the iconic tri-color layout has been opened up to reveal the silicon escapement, beating away at 36,000 vibrations per hour. The updated 39.5mm steel case houses the El Primero 3604, a self-winding movement that drives a central chronograph hand capable of circling the dial every ten seconds. Finished on a blue leather strap, this Chronomaster Open suits those who want a front-row seat to what makes the watch tick.

This is a pre-owned Zenith Chronomaster Open Steel Watch 03.3300.3604/69.C823. It comes with papers, a leather cardholder, a leather booklet holder, and the manufacturer’s box.
