On 17 June 2017, the evening before the culminating day of the Prix de Diane Longines featuring the world's biggest race for fillies, the Swiss watch brand officially launched the new blue model of The Longines Master Collection in the heart of Paris. This stainless steel model displays a sunray blue dial, a fashionable chromatic variation, and belongs to a collection, which is one of the brand's best sellers since 2005. Besides, Longines is proudly presenting as the Official Watch of the Prix de Diane Longines the new lady model with diamond indexes and blue alligator strap matching its blue dial, which happens to be the corporate color of the winged hourglass brand. The watchmaker is associated with the event at the Chantilly racecourse as its Title Partner and Official Timekeeper for the seventh time.
