This Bulova mens watch from the Maquina collection offers daringly avant-garde design. The watch features a 40mm rose gold- and silver-tone tonneau-shaped stainless steel case with a double-curved sapphire crystal, a blue bezel, and a blue HNBR rubber strap with a pin-buckle closure (move further down). The blue patterned dial with black dial ring and bridges has rose-gold tone hands and markers with luminescent fill and a central aperture revealing the inner workings of the 21-jewel automatic skeletonized movement, also visible through a transparent case back, which has a 42-hour power reserve. With its mechanical heart and unrivaled modern form, this Bulova mens timepiece offers a uniquely bold individual expression of style.
