Breitling Superocean R17375211B1S1 42 mm Black Dial

The Superocean R17375211B1S1 gives the 42 mm diver a case in 18K red gold, set against a black dial and black strap. At 12.56 mm thick and 157.92 grams, it retains the compact proportions of the smaller Superocean format while adding the visual weight of precious metal. A unidirectional bezel, screw-down crown, sapphire crystal and solid caseback support the 300 metre rating and keep the watch's aquatic purpose clear.

Its automatic Breitling Calibre 17 is based on the ETA 2824-2 and uses a bidirectional rotor. Hand-winding, hacking seconds, 25 jewels, a 4 Hz frequency and a 38-hour power reserve define the movement, which presents central seconds and a date. That focused calibre places the red-gold reference naturally within the Superocean time-and-date family, where the case material provides the principal distinction.
