A ref. 18038 Day-Date with a spectacular Onyx dial. Onyx dials are made of natural stone and, from this time, absent of any indices whatsoever. They also distinguish themselves from standard Day-Dates with faceted, framed gold aperture surrounds. This example has no hairline fractures whatsoever and is signed Swiss alone, as it should be. Originally property of a Venezuelan collector, this example comes with a Spanish Day disc and Spanish papers.
