Housing a new El Primero caliber, 4007C, the Zenith Mega Port Royal Tourbillon joins the Zero-G Tourbillon at Baselworld in presenting new calibers for the El Primero and opening up new vistas in the manufacture’s repertoire.

The case is in black titanium and sports a protective grill across the sapphire crystal that is meant to offer additional protection to the crystal. What makes this piece interesting though is the introduction of an anchor in silicon, marking a major milestone for the manufacture and a wholly unanticipated one at that. 

The tourbillon carriage ‘sits behind bars’ at the 11 o’clock position, and makes one revolution per minute. The Grande Date version features a patented three-disk system that is yet another mechanical advancement from the brand this year. Case specifications are not yet available, at press time.
