Oris Watch Divers Sixty Five Chronograph 01 771 7791 4054-07 8 20 18. Oris is pleased to introduce a fresh expression of the mid century inspired Divers Sixty Five Chronograph, our ever popular retro divers watch. The new model has a smaller 40 mm case and a refined monochromatic dial design, and comes with the option of a black leather strap crafted in sustainably sourced deer leather by our Swiss partner Cervo Volante or a stainless steel metal bracelet. The base design echoes our first divers watch of 1965, a visually pared back but highly competent piece that captured the spirit of an exciting new era when recreational diving was becoming increasingly fashionable. The two counter chronographs silhouette is defined by its sweeping lugs, muscular uni directional rotating bezel and distinctive vintage chronograph pushers, while its powered by an automatic mechanical movement with a 48 hour power reserve.
