Patek Philippe has always been generous in providing resources for the advancement and research of technology and horology. In 1948, Patek Philippe inaugurated its Electronic Division, with the goal of innovating photoelectric and electronic timekeeping technology. In 1955, the firm showcased a solar-powered photoelectric clock at the World Symposium.

The Dome Clock not only displays beautiful art, but merges timekeeping with technological innovation. It is the perfect canvas for an artisan to showcase his or her ability to create beautiful paintings. To apply enamel on the curved panels requires extremely delicate handling and high technical ability, as enamel is particularly prone to cracking. The relatively vast space furthermore enables the artisan to exhibit a wide range of color and design.

The present example is inspired by Vivaldi's Four Seasons, as confirmed by the Extract from the Archives. The background is painted with luscious varying hues, ranging from swathes of deep forest green, to rich burgundy. Each panel showcases the wilting or waning of flora, depending on the season. The flowers are scattered throughout, providing vivid pops of color. The artisan’s use of gold cloisons is particularly impressive here, given the number of delicate flowers and leaves rendered throughout the clock.

Signed "EPL", the enamel work was most probably created by Elisabeth Perusset Lagger, one of Patek Philippe's best enamelists. Elisabeth Perusset Lagger is particularly well known for rendering images of nature.

The clock itself is preserved in astounding condition. There is no restoration to the panels, and the enamel remains intact, exhibiting its rich hues with no losses. Dome Clocks are increasingly collectible and valuable today, due to their rarity and technical superiority. To find one like the present example, still retaining its original fitted presentation box, is nothing short of extraordinary.
