Z BONE is the fourth ZULU timepiece drawn in the studio rather than specified from a supplier catalog: a skeleton automatic on the NH72A caliber with the dial cut away to the movement's full opening. Forty millimeters of 316L stainless steel on a five-link bracelet, anti-reflective sapphire, BGW9 luminous, sealed to one hundred meters, and an exhibition case-back engraved with the studio coordinates. The dial is a solid outer ring carrying eleven applied markers and a full railroad, with a spine running twelve to six and the meridian pressed into it. Offered in three configurations, Feed, Soot, and Steam, as a limited MMXXVI cohort, each configured to order and delivered with a hand-signed certificate of authentication. Every order ships with a RealGoat19 challenge coin and free shipping.
