Powering this large-model Santos is the Manufacture calibre 9612 MC, a manually wound mechanical movement composed of 138 individual parts — including 20 rubies — and individually numbered. The movement measures 28 mm × 28 mm with a thickness of 3.97 mm, operates at 28,800 vibrations per hour, and delivers an approximate power reserve of 72 hours. The case, finished in black ADLC steel, extends to a thickness of 9.08 mm and offers water resistance to 10 bar (approximately 100 metres), with a sapphire crystal and sapphire case back framing the view.
The skeletonised bridges form Roman numerals across the open dial, while polished grey steel sword-shaped hands — treated with luminescent material — ensure legibility. The 7-sided crown is set with a blue synthetic spinel, a hallmark detail of the Santos lineage. Straps are provided in both blue and black calfskin, each compatible with the QuickSwitch interchangeable system and secured by a black ADLC steel double adjustable folding buckle.
