KENTUCKY DERBY COUNTDOWN: Luxury Swiss watch manufacturer Longines will resume its role as official timekeeper of the 138th annual Kentucky Derby at Churchill Downs for a second year this May. The brand will be awarding chronograph watches from its new Saint-Imier collection to the winning Derby team — owner, trainer and jockey — and will have a strong presence throughout Churchill Downs and other Derby-affiliated events, including the Longines Kentucky Oaks fashion contest on May 4th. Women in attendance at Churchill Downs on Kentucky Oaks Day can enter for a chance to win a Saint-Imier watch in stainless steel and rose gold with diamonds, along with an all-expense-paid trip to New York City for Mercedes Benz Fall Fashion Week in September. Judging the festivities will be tennis star Stefanie Graf, E! Entertainment Television’s Catt Sadler and NBC “Fashion Star’s” Jeannie Mai.
