The Holy Trinity, also known as The Big Three, is the name given in horology to three luxury watch brands. [1] The watch brands are Patek Philippe, Audemars Piguet and Vacheron Constantin. The classification dates back to the 1970s. [2]
The application of the term "Holy Trinity" -a concept with religious origins in Christianity- to these three companies is based on meticulous craftsmanship of their hand-crafted products, as well as the prestige tied to their long-histories in the Swiss watch industry [3] (founded in 1839, 1875, and 1755, respectively).
