In 2025, the world will celebrate the 300th anniversary of Antonio Vivaldi's cycle "The Contest between Harmony and Invention," which includes the famous concertos "The Four Seasons." This philosophical dialogue between tradition and innovation continues to inspire today, reflecting in the work of Konstantin Chaykin — an outstanding contemporary master-inventor.

In 2019, Chaykin applied for a patent for the design of an eternal calendar, featuring four mechanisms dedicated to the seasons, with indications of the months and dates of the season. In 2021, he received patent No. 037160, planning to complete the work by 2025, but the project was postponed.

Today, Chaykin has found a new way to realize his idea through painting. The artwork "Autumn” created by the master, translates the invention into an artistic form. The warm mixture, which uses a combination of gold and steel with rare inclusions of ruby brilliance, creates the atmosphere of early autumn — golden foliage, sunlit days, and the first frosts. The central theme of the painting is the calendar module "Autumn" for the clock series "The Four Seasons”
