What Makes This Watch Special
This model features a 300m water resistance and is powered by the automatic "Elite 670" movement with an approximate 50-hour power reserve. It is a faithful reissue of the iconic "Defy A3691" first introduced in 1969, meticulously recreating its unique design and details based on the original blueprints. The striking octagonal case and 14-faceted bezel combine for a distinctive look, while the vibrant deep red gradient dial adds visual impact. The square applied indexes with horizontal lines set this model apart, and the steel "ladder" bracelet by Gay Frères ensures a comfortable fit while preserving the original's spirit, making it a must-have for both vintage enthusiasts and modern watch lovers.
