The present lot, reference 5712R-001, is a contemporary wristwatch dating to 2009. The case and is crafted from 18k rose gold and has a standard 3 part construction, rather than the original monobloc case. This allows for easier serviceability and a sapphire case back to view inhouse Caliber 240 PS IRM C LU.
