The Hermes Slim d'Hermes | family history
The Slim d'Hermes is where Hermes's watchmaking credibility is most directly expressed: the H1950 caliber is manufactured by Vaucher Manufacture Fleurier, in which Hermes holds a significant minority stake. At under 4mm movement height, the Slim d'Hermes PM is a serious thin watch, not a licensed fashion piece.
Hermes' ultra-thin platform, produced at La Montre Hermes in Bienne with in-house movements built around minimalism. At 8.35mm total thickness, the Slim d'Hermes PM competes with Piaget and Cartier in the ultra-flat dress category.
2015 · Launch and the Vaucher partnership
The Slim d'Hermes launched in 2015 as Hermes's first watch to carry a movement from Vaucher Manufacture Fleurier. Hermes's stake in Vaucher (acquired over the 2000s) represents a genuine investment in manufacture-level watchmaking. The H1950 caliber was developed specifically for the Slim, not procured from an open-market supplier.

How to read this family
What to consider before buying a Slim d'Hermes.
- Is this a legitimate ultra-thin or just a fashion piece? Legitimate. The H1950's 2.6mm movement height places it in the company of dedicated ultra-thin calibers from AP, Piaget, and JLC. The Vaucher manufacture relationship is real and the watch specification is serious. It is also a Hermes design object; both things are true simultaneously.
- How long does 116 hours of power reserve actually last? Hand-wound movements require winding; 116 hours is approximately 4.8 days. In practice, wind it daily or every other day and the reserve is irrelevant. The long reserve exists as a specification credential and as a practical buffer if you forget. It does not change how you interact with the watch.
