Audemars Piguet Royal Oak in Platinum

This is a killer Audemars Piguet Royal Oak reference 56175PT in platinum circa 1990. The original factory diamond dial is incredible. The dial has turned a beautiful brown/coppery color. A color almost hard to describe. The dial has very understated factory diamond hour markers. Aside from the dial, this watch being platinum is also very special. The case and bracelet are both in excellent condition. We believe both the bracelet and case to be unpolished showing normal light wear. This 1990's watch is powered by a quartz movement. This is a very unique Royal Oak.
