Overview
White layered composite with a black skull
The bezel and caseback are a white layered composite, with the skull left dark so that it reads sharply against the pale case. The strap is black rubber.
The construction is the RM 52-01’s: a tripartite case around a calibre RM052 whose baseplate and bridges take the form of the skull, the jaws holding the ruby of the tourbillon cage.
