The dial is a \"split\" design, vertically bisecting the aesthetics of the first and second Lupin editions; the left side features a semi-matte black finish with grey sub-dials, while the right side is creamy white with black sub-dials. This reference is the first time Zenith combined two distinct dial patterns into a single production watch. On the secondary market, prices typically range between $15,000 and $22,000.

This specific platinum execution is distinguished by its weight and a silver or blue sunray dial, often featuring applied rhodium-plated indices. Unlike the more common steel variants, the platinum version was produced in limited quantities, representing a high-end complication from the brand’s transitional era. On the secondary market, these pieces typically trade between $12,000 and $18,000 depending on the presence of the original platinum deployment buckle and service history.
