DESCRIPTION:
2026 Zenith Chronomaster Open reference 03.3300.3604/69.C823 in like new, barely worn condition with complete fullset. The Chronomaster Open bypasses the traditional solid dial to reveal the high-frequency mechanical engine at work — part of the tricolor layout is opened up to show the silicon escapement beating at 36,000 vibrations per hour. 39.5mm stainless steel case, matte silver dial with tricolor sub-counters including a transparent running seconds counter. Central chronograph hand completes one revolution every 10 seconds for 1/10th-of-a-second timing. Blue cordura-effect rubber strap with stainless steel triple folding buckle. Sapphire crystal, anti-reflective. Sapphire exhibition caseback. Water-resistant to 10 bar.
Powered by Zenith in-house Calibre El Primero 3604 — a modified El Primero 3600, 35 jewels, 36,000 vph (5Hz) via visible silicon escapement, approximately 60-hour power reserve.
Purchased directly from Zenith’s website — the warranty card carries no authorized dealer stamp or printed purchase date, but the manufacturer warranty is confirmed to have begun July 8, 2026 and is valid through July 2031.
