Brand comparisons usually run on opinion. This one runs on settled transactions: 400 recorded sales of Piaget and 244 of Heuer, all in US dollars so the figures are directly comparable.
What each one actually costs
The median Piaget result is $5,250. The median Heuer result is $5,000. On typical examples, Piaget carries roughly 1.1 times the price of Heuer at auction.
Half of all Piaget sales land between $3,570 and $10,240. For Heuer the middle half runs $2,750 to $12,500.
Which one surprises the specialists
41% of Piaget lots beat their high estimate, against 30% for Heuer. That gap says the trade is more often caught out by Piaget, which is a sign of demand outrunning the published guide.
Breadth of the record
Our archive covers 156 distinct Piaget references and 75 for Heuer, with results going back to 2001 and 2001 respectively. The top recorded result is $602,500 for Piaget and $199,500 for Heuer.
What this does not tell you
A median is not a verdict. These brands overlap heavily at the edges, and a well chosen example of the cheaper one will outrun a poor example of the dearer one. Condition, completeness and model matter more than the badge on the dial.
