AUDEMARS PIGUET ROYAL OAK 4100BA – 18K YELLOW GOLD – CHAMPAGNE DIAL – DIAMOND INDEXES

AUDEMARS PIGUET ROYAL OAK REFERENCE 4100BA – 18K YELLOW GOLD – CHAMPAGNE DIAL – DIAMOND INDEXES

The introduction of Audemars Piguet's Royal Oak model marked the beginning of the sports watch trend we know today. In 1972 it was presented at the Basel Fair and turned out to be the most expensive steel watch that had ever been announced.
The interesting and in some ways nice aspect is that, even today, the Audemars Piguet brand is mainly known for its Royal Oak models, which were not considered at the time of the first presentation.
The following model of Royal Oak reference 4100BA is considered to be a particular model due to its configuration which sees it being entirely in 18K yellow gold with diamond indexes and a rather unusual size for this model, 36mm.

This Audemars Piguet reference 4100BA model has the following features:

18K Yellow Gold Case and Bracelet
Tapisserie Champagne dial
Indices in Diamonds
