Invicta Pro Diver 20434 40mm automatic – stainless steel case and bracelet with blue sunburst dial and open heart display.
Classic and refined, this Pro Diver delivers automatic timekeeping through a Japanese NH38A caliber movement visible both through the exhibition caseback and the open heart window at 9 o'clock. The striking blue sunburst dial features luminous hands, applied hour markers, and professional markings beneath hardened crystal. A unidirectional rotating coin-edge bezel enables precise dive timing, while 200-meter water resistance with screw-down crown ensures reliability for serious aquatic pursuits.
