Zenith 30.3400.3610/63.C916 description
The Zenith Chronomaster Original Triple Calendar 30.3400.3610/63.C916 debuted in 2025 as a Japan-exclusive edition limited to 55 pieces, characterized by a malachite dial combined with an 18K yellow-gold case. The case measures 38.00 mm in diameter, is water-resistant to 5 ATM, and is fitted with a cordovan leather strap and folding clasp, compatible with the interchangeable-strap system.
The natural malachite dial gives each watch a distinct pattern due to the material’s inherent variations. Timekeeping is handled by central hours and minutes with small seconds at 9 o’clock. The 1/10th-of-a-second chronograph uses a central hand completing one rotation in 10 seconds, supported by a 60-second counter at 3 o’clock and a 60-minute counter at 6 o’clock. Additional indications include a complete calendar with day, date, and month, as well as a moon-phase display.
The watch is powered by the El Primero high-frequency calibre, operating at 36,000 vph (5 Hz) with an approximate 60-hour power reserve. The movement comprises 366 components and integrates the triple-calendar and moon-phase mechanism into the El Primero architecture.
