An authentic seagoing instrument, this aptly named model is distinguished by its broad ratcheted bezel featuring a highly professional style including black rubberincrusted numerals and markings; as well as by its oversized twin day-date windows. 

The case displays a satin-brushed finish on the top as well as polished sides; its sturdiness and its water-resistance to 500 m (1,650 ft) are enhanced by a screw-locked crown with protective reinforcements and by pushpieces that cannot be activated until they are unlocked.

The large Arabic numerals and hands with a luminescent coating combine with a thick sapphire crystal glareproofed on both sides to guarantee optimal readability in all circumstances. The Superocean Chronograph Steelfish special edition is available with a black, silver or blue dial and fitted with a steel bracelet or rubber strap. To preserve optimal precision come hell or high water, it is equipped with a selfwinding chronograph that is officially chronometercertified by the COSC (Swiss Official Chronometer Testing Institute)  as indeed are all Breitling movements.
