This Bulova mens watch from the Maquina collection offers daringly avant-garde design. The watch features a 40mm gun metal- and black-tone stainless steel case with a curved sapphire crystal and a gun metal-tone stainless steel bracelet with a push-button deployant closure. The green patterned dial with black dial ring and bridges has black hands and silver-tone markers with luminescent fill, with a central aperture revealing the inner workings of the 21-jewel automatic, also visible through a transparent case back, skeletonized movement which has a 42-hour power reserve. With its mechanical heart and unrivaled modern form, this Bulova mens timepiece offers a uniquely individual expression of style.
