The Holy Trinity (also The Big Three) is an informal marketing term in high-end horology collectively referring to three heritage luxury watch brands: Patek Philippe, Audemars Piguet and Vacheron Constantin. [1] The term dates back to the 1970s, [2] while the brands were founded in 1839, 1875, and 1755, respectively.
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]
