Reference A13312121B1S1 brings together a 46mm stainless steel case accented by black ceramic and a deep Volcano Black dial. Index hour markers are tipped with luminescent dots, while large silver-tone luminescent hands sweep over a layout that includes a date aperture at 3 o'clock, a 30-minute counter sub-dial at 12, a 12-hour counter sub-dial at 6, and a small seconds sub-dial at 9. A cambered sapphire crystal, glare-proofed on both sides, sits above the dial, and the case is secured by a solid case back with screw-locked, dual-gasket water resistance to 200 m / 660 ft.
The black ceramic unidirectional ratcheted rotating bezel frames the case, and the movement within is the COSC-certified Breitling Caliber 13 — an automatic chronometer with 25 jewels and approximately 48 hours of power reserve. A black Aero Classic rubber strap with a push-button fold-over deployment clasp keeps the watch securely on the wrist during professional-grade use.
This piece is unworn, with authorized-dealer protective plastics removed, and is presented complete with the original Breitling box and papers along with a Breitling warranty.
