Manufacture d’Horlogerie refers to a watchmaking company that is involved in the complete process of creating timepieces, from the initial design to the final assembly. This term is often associated with high-end, luxury watch brands that pride themselves on their ability to produce in-house movements and components, ensuring a high level of craftsmanship and quality control. A true Manufacture d’Horlogerie is distinguished by its capability to design, produce, and assemble the majority of the watch components, including the movement, case, and dial, within its own facilities.

This vertical integration allows for greater innovation and customization, as the company has full control over the materials and techniques used in the production process. It also enables the brand to maintain a unique identity and heritage, as each watch is a reflection of the company's expertise and tradition in horology. The term is often used to denote prestige and exclusivity, as watches produced by a Manufacture d’Horlogerie are typically limited in quantity and crafted with meticulous attention to detail. Collectors and enthusiasts value these timepieces for their technical sophistication, aesthetic appeal, and the legacy of the brand behind them.
