Luxury watchmaker Vacheron Constantin has auctioned off what it calls "an exceptional gentleman's watch" made out of platinum to mark the company's 250th anniversary.

The Swiss firm has now sold the watch - entitled Saint-Gervais - in a record-breaking auction underlining the exclusivity of the precious metal.

The platinum watch, which includes a perpetual calendar and boasts a 250 hour power reserve, fetched a staggering 446,250 Swiss francs ($374,000).

Antiquorum hosted the Quarter Millenium of Vacheron Constantin auction, with the auction house chairman Osvaldo Patrizzi hailing the oeuvre on show.

He told JCK the auction had underlined Vacheron Constantin's "importance in the world of watch collecting and reaffirms its place in the top echelon of watch manufacturers".

A total of 250 items were auctioned to commemorate the firm's anniversary, with the $15 million sale taking place in Geneva.
