Following the success of the Santos de Cartier Skeleton released last year, the French maison released a new iteration of this watch at the SIHH 2019. The unmistakable design of the Santos de Cartier with its square case and exposed screws gets even better in the new Santos Skeleton Noctambule with its ADLC steel case —measuring almost 40 mm wide— and skeletonized bridges with superluminova, that at the slightest dimming of the ambient lights glows like a powerful greenish lantern.
