The brand of the most expensive watch in the world?

The most expensive watch in the world is not made by Haute Horologe.

From a factual, collector’s point of view:

Brand: Graff

Watch: Graff Diamonds Hallucination

Estimated value: around USD 55 million

Why: it is a high-jewellery timepiece set with extremely rare, multi-coloured diamonds. The value comes more from gemstones than traditional horology.

From a pure watchmaking and collector perspective, the title most enthusiasts respect is different:

Brand: Patek Philippe

Watch: Henry Graves Supercomplication

Sold for: USD 24 million (at auction)

Why it matters: mechanical complexity, history, and craftsmanship not diamonds.

Important clarification about Haute:

Haute Horologe is not a watch manufacturer. It is a specialist platform and curator in the pre-owned luxury watch space, focused on fine watchmaking brands rather than producing watches itself.
