Encased in 46mm of stainless steel, the Zenith El Primero Chronomaster Grande Date Full Open includes an automatic El Primero 4047B movement with a moonphase at 6 o'clock and a big date at 2 o'clock. A sapphire crystal dial offers a full view of the self-winding caliber, while SuperLuminova SLN C1 coated hands display the time. This reference, 03.2530.4047/78.C813, was originally paired with a calfskin strap, which has since been updated to alligator.
