Breitling Superocean Heritage II AB202012/BF74/256S 46mm – Black dial dive chronometer with rubber strap.
A modern diver forged in Breitling's aviation heritage, this 46mm automatic chronometer blends vintage dive-watch character with COSC-certified precision. The polished stainless steel case frames a volcano-black dial with luminous index markers, protected by cambered sapphire crystal glareproofed on both sides. A black ceramic unidirectional bezel, screw-down crown, and 200-meter water resistance ensure professional diving capability, while the Caliber B20 movement delivers exceptional timekeeping with a generous 70-hour power reserve.
