In the 1980’s Patek Philippe made a very small number of Grande Complication watches, in the tradition of the celebrated one made during the last century, as exemplified by the famous ‘Gradowski’ watch. While remaining faithful to tradition, these watches also benefit from the best that modern technology can offer. Each piece is slightly different, but all are based on the same 20”’ movement. All are superbly finished and represent the ultimate in highly complicated timepieces.

The Seal of Geneva Quality Mark is a trademark of the Office of Geneva Control of Watches. It was established on November 6, 1886, amended several times with the largest change incorporated on December 10, 1955. Its function was to voluntarily control watches made in the Canton of Geneva. Paragraph 3 of the statues states that the watches awarded the Seal of Geneva Quality Mark must “after examination prove to have a perfect mechanism to ensure regular and durable functioning”.
