The present example belongs to the reference 3900 which was in production for only a very short period. Traditionally, scholars and researchers have only recognized the reference 3900 in stainless steel, steel & yellow gold, yellow gold, and platinum. It is the first example of reference 3900 in 18K white gold which appears to the public.

Our research shows that the production of reference 3900/1G was very confidential, and the watch was very likely a custom order. The watch is fitted with sunburst matte black ribbed dial, lavishly adorned by 11 diamond hour-markers — the dial configuration that is usually reserved for its platinum examples. The 18K white gold case material, dial configuration and production year are all confirmed by Patek Philippe’s Extract from the Archives, demonstrating that the watch is all original. The case has never been polished and the hallmarks are crisp and clear.
